If yyou have some real bad connections and you need to solve thisou have voltage drops when you open the door you got a short problem. there is no way that you should have no more than 1.5 volts of load on the system. even turning all the lights the heater stereo a/c and everything else would put that kind of load on your electrical system. i would deal with the electrical problem first. then go get another deck because chances are your input power module is no good in the deck. before replacing the deck in vehicle make sure you have no more than 1 volt of load drop in that circuit.
It think you should investigate this relay closer i am assuming this was installed at the dealer as an option?, my guess would be where they tapped into for power for the changer control under the dash is controlled by this relay for the interior light circuit(auto dimming), the memory circuit in the changer cannot operate on the 5v (dimmer control) and you are loosing your memory, i understand you don't want to take apart the dash but i have a feeling you will find your problem where they have jacked into for power under the dash.. i would locate that and remove it from this auto dimming circuit, and run another 12v constant feed to the changer sorry i cannot offer you a diagram but i think you will find the problem as you seem very determined and quite qualified please rate -jeff
Can you tell us if the radio is keeping station memory etc? and time?
there is a chance your cd player is set up to always start from 1 (yes there are some out there).
maybe the head unit seimens wont talk properly to the blaupunkt stacker? try a blaupunkt head unit?
i would suggest running a new memory wire to the head unit.
let us know how this helps
If you supply wrong voltages to CD changer you get a fault most of the times, not only not keeping memory.
The radio (not hthe changer, the stereo itself) has a memory input, I think it is +5V, If it had not been connected it will reset the CD memory also, check the back of the radio and find power for memory settings.
If it is not connected or connector is bad, that is the problem.
Regarding CD changers, they do not have a pin for memory, (see below ) they communicate with main unit like a computer on USB, with their own protocol.
If they do not keep memory, either depends on main unit (most common) or rarely the cd changer may be faulty.
" I have replaced the cd changer and the radio/cd and problem persists"
This is because the problem is not the CD changer, or the CD changer wiring.
The problem it is in the radio wiring, the memory positive supply cable connection is not working, then radio lose memory of CD changer position.
Tell me your radio model, I see if I have wiring for it, you must be quick as I am going offline, or ask to one of the others.
"There is a yellow wire on pin 7 which has got 12 volts with the car
ignition off and the car door closed which goes down to 5 volt with the
car door open, and restores to 12 volt a few seconds after the car door
is closed - there is another orange wire on pin 7 which works exactly
the opposite"
That is also a problem, That is a contact! each time this happens you reset the cd changer same as if you disconnect battery cable.
Remove door panel, or whatever you need to remove and fix the bad wiring first, otherwise is useless troubleshooting.
Check also your car stereo wiring on the manual and see if memory + cable is present, otherwise you reset the radio each time you restart the car.

One wire to remove, the original wire going to pin 9. In lieu of that, put a jumper wire from pin 9 to the white wire ensuring that the white wire is getting an always on B+12.
In such a case it is always found that the adaptor led is faulty.
please do get it checked or replaced.
please do rate the solution

try local car mechanic instead of compant service technician.it would be quiet cheaper.and also not take so long to get it done.just you have to be him all the procedure that he does not damage or replace any part without letting you.the technician on site is vwry much necessary in your case.as the wiring diagram for your device is not available.
thanks.

The voltage should always be constant through the red wire which is a 12/14 gauge in size. when you turn the key the voltage should flow to the deck to power it up. this should also be 12/14 gauge. this is the accessory circuit.. now i read that when you open your door opens that the voltage drops. which wire does the voltage drop from? the yellow or the red. this is important because if it drops from the circuit of the red wire you have a draw on the system form something that is unrelated to you stereo deck but enough that it draws too much voltage so that your memory cuts out.
ok if you have just yellow and orange wires the yellow is constant and the orange is the accessory. blaupunkt is a german manufacture and they don't always use the same wire codes we do in the states, however you should go and get a replacement harness that matches the factory connector of your vehicle to the stereo deck these are very specific the shunt that you have is faulty. if you have constant current with the car off and you have current with the key turned on and you lose memory it is not the vehicle circuit it is either the harness adapter or your stereo deck and if it is the deck then it is an internal and most likely the power supply module on the circuit board...........please rate this............thanks

Replace the part
Unplug its wiring harness connections, inspect, make sure contacts are ok, reconnect according manual instructions and try again. Make sure also loop play is not displayed.
The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them.
hope this may help;

The yellow wire needs a constant 12 volts to maintain memory. It drops to 5 volts and thus causes a reset of the changer and that is why the memory is lost. Connect that wire directly to the battery. Then you may want to find out why that wire drops to 5 volts, it could be a problem in another part of the electrical system. It should not be dropping to 5 volts when you open the door. That is your problem. Once that wire is directly connected to the battery, your memory problem is solved, but you will have another problem somewhere else iin regards to the door opening and it drops to 5 volts.
Let me know if I can be of any more help.
The cd changer needs a full 12 volts to keep it's memory. If it drops below a certain threshold it will consider it as not being there and then when the voltage comes back it initializes as if it was just connected. As i stated before, if you run this wire that is dropping in voltage directly to the battery it should solve your memory loss problem. then you would need to find the problem with the door opening and causing it to drop the voltage. It could be a switch that is getting loaded down somehow, but it does seem to be the problem for you.

It could be few things but
>1st try the fuse panel in your car the fuse for the radio memory could be blown or lose(check the car manual for the Location of the RADIO MEMORY FUSE)
>The stereo buttons on the front can get stuck so if this is the problem and the REPEAT is stuck or shuffle ETC. JUST make sure to see if the buutons are all working.

IF you do not have the correct wire harness for your car do you mean the Stereo Harness from the head unit is a not the factory one so you have a 3rd party Harness that fits your cars harrness BUT it was not MADE for your car...I read the post and and It seems that one of the wires are just switched (REMOTE:Blue Or YElLOW anttena or common but the Menory REd with White Strip or (ACC +) can also be switched. PLEASE if this is what you are try to figure out then plese post. This will help narrow your problem>
Need more info (POST)
You still are have not fixed it--ok well I have been trying to look for the specs on your car and so far no luck I will continue looking for the wiring diagram...but in the mean time have you tried to
>locate this (RELAY) that you hear "place your finger on the (RELAY) it will vibrate/buzz
>Remove the (RELAY)and locate the same EXACT (RELAY) on the fuse panel and switch it to another "AUX" {what you want to know is if the (RELAY)is faulty.

>PUT all (RELAYS) back but this time "leave the one slot empty"
the door one etc.
>Now run the CD changer like you normally have been and see
if the voltage still is dropping

>I want to repeat this process untilyou find which (RELAY)is causing this
>NOW if you do find the location of the (RELAY) put back all other (RELAYS)
> NOW keep the (RELAY) out of this slot and do as you normally would see if any thing changes: NOTE: you might have to reprogram the RADIO/CD Changer
>If it worked bad (RELAY)
> if it did not work than you need to see if the voltage is still dropping and it could also be a (FUSE) that is the problem
REPEAT the steps above but this time locate the (FUSE)
you should be able to locate the (FUSE) for the door in the car owners manual this will be faster I would remove the (FUSE OR FUSES) that are on the door AUX (interior light, and the BUZZING FUSE that lets you know that your keys are still in the ignition
>This should help you narrow down the source of the problem
so it could be 1 or 2 things
>1 the the (RELAY orFUSE) or bad need to replace
>2 the wiring of your stereo or cd changer is WRONG and
there needs to be a wiring diagram to connect the wiring to the correct location
I have really thought about this and I have worked on installing car stereo for several years. This is a rare event and I have never worked on tat brand of a car.
FINAL NOTE: if you have a voltage meter i would test all the wire leeds to make sure that are getting 12v etc.
I hope you have better luck this time
please rate you FixYa Expert Kindofcheap
You only need to remove the FUSE from the fuse panel the manual will tell you what fuse# is link to the door AUX light or Interior Dome light. This is going to tell you if the CD CHANGER is tied in to that fuse....Note: it should not be if it is than your ACC+ power is going to the wrong FUSE! PLEASE understand that the fuses are a common for the owners to replace and check. This is not going to damage anything by remove the FUSE. Thank You
I have ran out of suggestions and that car has been very hard to find any info on . If any thing your local audio car install center has a program that list all makes and models DIAGRAMS. They may or may not charge you to print this out for you. I really tried and without full details in front of me I can give you my EXPERT ADVISE

Question: Was it working before?
Verify that the CD Changer is
properly connected to the vehicles body harness. Double check the fuse relay. Turn the vehicles ignition switch to Accesssory.
NOTE: See owners manual of the CD Changer
for more information on controlling the changers operations through the
vehicles radio.
When u hooked it up there should have been a yellow wire for the memory that runs with the hot wire so that the system will hold its memory
Sir,
sounds like your cd changer isn't hooked up to a constant 12 volts that is holding the memory. or your cd player isnt.
thanks
good luck
Can you look for another posibilities that may occur the problem. like your settings on the menu. it must be played repeatedly.

Upgraed the ram your problem will sloves

Resolve Memory Loss
Thanks
The problem may be because the contsant 12V and the memory
12v need to be changed over, the wires should be the red and yellow, if
i remember rightly.
if you look at the plug face on, the yellow wire is top second on the right, and the red is second line down far right.
Please rate the solution.

Hi,
As in most memory circuitry, there needs to be a constant B+ supply. Pls check the connector terminals with a DVM. With no key in the ignition, at least one of those connectors/terminals/wire should have an always on +12. If none, then it would be required to doubleback the harness to its origin and determine which of the wires is disconnected.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
Appreciate the postback and additional information.
The +12 going down to +5 is significant. Technically, what you measured as +12VDC on pin 7 is a no load voltage, meaning there is no current flow. Once there is a load (current flow) such as the CD changer then the voltage goes down. It would seem that the door light circuitry is somehow interconnected.
Proposed course of action:
Would appreciate further update at your convenience.check again the +12 on pin 7 but put in parallel to the test prods of the DVM a small peanut bulb 12V with wires. The idea is to check for the presence of 12VDC with a load;
follow the harness to its origin and determine where it is spliced to;
it is highly possible that you have a loose connection to and again possible that the same wire is used by the dome/door light;
another possibility (though remote) is a loose ground;
a temporary workaround/test to establish missing always on +12 is to hardwire a length of autowire from the + battery terminal to the CD changer;
it may also be worth your while to check for loose fuse connector, terminal connectors and jumper strips. Often scraping them clean or bending a bit improves contact.
Cheers.
Sorry but now I am confused.
Your post "...a yellow wire on pin 7 which has got 12 volts ... another orange wire on pin 7 which works exactly the
opposite..."
Two wires on the same pin with different voltage readings?
On to the CD changer, is the connector circular or squarish, does it have 8 or 10 pins?
Is the yellow (pin 7) on the bottom left of the connector?
and finally...
For some reason, documentation for a Blaupunkt ISD A04 CD Changer is pretty hard to source. The closest I was able to check was a 12 pin Ford ACP connector here with details what goes to what pin.
Additionally, for an ISO standard connector, the Blaupunkt 12pin connector was not readily available among the standards..
Back to the 12pin Ford ACP, pls reference above link for pinout out. To verify compatibility, pin 3 is ground, pin 4 has no connection, pin 8 goes to +12 when CD is enabled from head unit and pin 9 is always on +12V.
Your idea of the +12 going to +5 as a standyby voltage has merit, however, I am in no position at the moment to confirm.
Pls verify above posted pinout voltages.
Your post "...somewhat thicker white cable connected to the head unit which has a steady 12V connected to it..." describes a relatively higher current capacity which is standard for the mains supply of the CD Changer, added that the other car's white wire is always on B+12.
Proposed solution:
Disconnect where your car's white wire is currently connected and re-attach to an always on B+12. Such may be found in the ignition switch connector. This attachment point may be verified with a DVM, ignition key off, there should be a +12.
Could you try on pin 9:
make it "no connection" by removing the original wire from the harness; and/or
removing the original wire from the harness and connecting it to thw white also.
one wire to remove, the original wire going to pin 9. In lieu of that, put a jumper wire from pin 9 to the white wire ensuring that the white wire is getting an always on B+12.

Maybe youvr set it up to loop on one song
The logic circuit that holds memory i.e. time and user setting has failed, the voltage it operates at is 10-18 volts, you will have to replace the head unit to correct this, Your local dealer can provide links to exchange the unit, then you just give them your old one and they provide you with a rebuilt unit, it's quick and easy.

my peugeot 207cc has got a Siemens RD4 head unit and a Blaupunkt A04 Cd changer. The problem is that when I switch off the car for a few minutes, the cd changer will not keep the memory and will always start again from track 1 cd 1. I have changed the head unit and even the cd changer and problem remains. I am suspecting that maybe the adaptor lead connecting the two together is defective in the sense that it is not supplying the right voltages to the cd changer ( ie steady battery, ignition etc.)Continuity of the adaptor lead is fine.
Yes 12V on pin 7 of the cd changer is present with the ignition off. A strange thing happens when I open the car door, ....this voltage decreases to 5V and whenever I open the car door, this sort of initialises the cd changer.
the adaptor shown does not fit my car - they seem to call it ISO - the cd changer takes a 12 pin plug
I do not think it is a voltage drop problem. There is a relay which I can hear operating whenever I open and close the car door. There is a yellow wire on pin 7 which has got 12 volts with the car ignition off and the car door closed which goes down to 5 volt with the car door open, and restores to 12 volt a few seconds after the car door is closed - there is another orange wire on pin 7 which works exactly the opposite - ie it has 5 volt with ignition off and car door closed and goes up to 12 v with the car door open and goes back to 5 V with the car door closed. I would like to know on to which pin should the steady 12 v be so that I can connect a lead directly from the battery to see what happens. Agfain I have a Blupunkt ISD a04 CD CHANGER connected to a Siemens RD4 head unit.
please note that I have changed both the head unit and the cd changer with new units and the problem remains. I would appreciate if someone can tell me to which pin from a 12 pin plug connected to the BlaupuNKT A04 cd changer should the memory steady 12 V is connected to.
excuse me for the mistake - yellow wire on pin 7 and the orange wire on pin 9.
It is a squarish type of plug with 12 wires
....as regards interchanging the yellow and red wires, I think we are talking about a different plug. Mine does not have a red cable and the yellow is not in the place mentioned
settings on the menu are ok. I listen to the cd changer - whilst motoring, the cd changer works normally. It changes to the next cd when the 1st one finishes etc etc. The problem is that if I switch off the car and leave it for a few minutes, the cd changer will not play from where it was when I switched it off but starts from cd 1 track 1 again. It sorts of re initialises.
see my previous posts
yes there is a yellow wire as in my previous posts - i am wondering if it is a characteristic of my peugeot 207cc that it reduces the voltage when switched off - maybe something they call 'economy mode'.
this was fixed by the peugeot dealer and it has always been this way. I am fed up of going to the dealer because they cannot get to grips with it. They changed my head unit and my cd changer with no success.
yellow wire is bottom left (pin 7) or top right depending how you look at the connector.
I can confirm pin 3 is grd, pin 4 no connection, there is no wire connected to pin 8, and pin 9 is the orange wire which behaves as explained previously.
The wire harness was obtained through the peugeot dealer. It is made by Valeo. It fits perfectly in the head unit ISO connector and then to the CD.
As I said the harness was obtained with the cd changer thru the peugeot dealer, and I am sure they obtained it thru their catalogues. I have compared the head unit wiring with another peugeot 207, and the connections are similar. The only difference I found is that there is a somewhat thicker white cable connected to the head unit which has a steady 12V connected to it, and which does not change with the closing and opening of the car doors. When checking this white cable on my car, this has the same characteristics as the yellow wire on the cd changer, ie 12V when the ignition is off and the car door is closed, but goes down to 5 V when the door is opened. I can hear a relay operating when I open the car door, and this relay closes a few seconds (maybe 30 sec) after I close the door, restoring the 12
I have connected a wire with a steady 12 V to the yellow wire of the cd changer but the problem persists. After a few minutes of engine shutdown, cd changer again starts from cd 1 track 1. The problem seems to be that the cd changer is re initialising everytime I open/close the car door. It seems to receive a multiplexed signal which I cannot pinpoint on which pins every time the door is opened/closed. Please note that I have already changed the CD changer to a new one.
...as I have said in previous posts, I have changed the cd changer to a new one
IO have connected a steady 12 v to this white wire but problem persists
I have already tried on pin 9 but left the original wires connected. So can you please tell me which wires to remove and where to apply the 12 V?
ok will do
please note that with the car switched off and doors closed, the 12 v is on the yellow wire on pin 7. Do you want me to remove pin 7 and replace it with a steady 12v (yellow wire) or pin 9 (orange wire)?
I have tried to locate this relay, but even though I can hear it in the glove compartment, I cannot actually locate it. Also, the car is still under guarantee, so I am a litte sceptic in starting to remove a lot of things to get at it. Please note that evcerything else in the car operates normally, including the cd head unit. This keeps the memory no problem. Also, other things like the instrumentation lights, etc operate normally with this same relay....ie they light up when I open the car door, and with the ignition off, they go off after a few seconds. What I cannot understand is why the cd changer re-initialises on openeing the door. What I can now add, which may help all the kind gentlemen helping me is that I think that the cd changer is actually holding the memory, because, if I switch the radio on after entering the car, it initially shows the cd and track number I switched the car off with....then the cd kind of re initialises and goes back to cd 1 track 1. Thanks everyone for your help till now.
I removed a fuse which according to the handbook says cd changer besides something else. When I removed this fuse, the headunit and the cd changer do not work at all. Funnily enough, I did a continuity check between the fuse connections and all the wires on the head unit and the cd changer - no continuity to any wire - more funny is that the same voltages as quoted earlier ( white cable on head unit, orange cable and yellow cable on cd changer) exhibit the same voltages present. At this stage, I would be grateful to the expert that can provide me with a wiring schematic of the peugeot radio system, and what and where should be connected to the blaupunkt A04 CD CHANGER.
i ALREADY CHANGED THE CD CHANGER AND THE HEAD UNIT
There is no gauge 12/14 red wire going to the head unit. The only wire with this gauge is a white wire, and it normally has the 12v with the ignition off and the doors closed./ The voltage on this wire drops to 5 V whenever I open tha car door in conjunction with a relay operation, and restores back to 12v a fes seconds after I close the door......but......should the cd changer re-initialise if there is a drop in voltage?
continuity check of the lead is good
thanks for your efforts
I will remove the yellow wire and install a new one - up to now I just connected the 12 v to the existing wire and fault remains. Will keep you informed
my friend as I quoted before, I have changed the cd changer and problem remains
Yes I have accessed this site - paid 13 dollars, but then got a answer that web page does not exist. I hope this is not a scam. Sent an email to their contact address
sorry did not understand your message
My friend I found out that even the main wiring going into the head unit (which is a siemens radio/cd) goes down in voltage when I open the car door - this does not happen on another peugeot 207 model
are u sure it is pin 9 and not pin 7?
what you are saying makes sense - the problem is that I have replaced the cd changer and the radio/cd and problem persists. I have checked the continuity of the extension and it seems ok.
The cd head unit is a Siemens RD 4 and the CD changer is a Blaupunkt A04. The car is a peugeot 207 cc
To give you more info, these are the pin numbers of how the two are connected. The cd/radio head unit has got what they seem to call an ISO connector, and the cd changer connector fits into it. The cd changer has got a 12 pin connector. These are the connections:
cd/radio head unit colour cd changer
1 brown 3
2 yellow 7
3 orange 9
4 blue 5
5 not conn.
6 not conn.
7 grey 1
8 cream 10
10 white 6
I do not think it is a voltage drop in the system. The drop is being done by a relay in the car......dont tell me why it happens because I do not know. I wish someone could enlighten me by obtaining the circuit diagram of a peugeot 207cc; the cd/radio connections; the connections that should go to a blaupunkt A04 cd changer. I think without these schematics, we cannot move any further.
yes the radio keeps station memory and also cd track number when you switch it off
I thought someone would have the circuit diagrams available....that could have helped
my friend the dealer just fitted the cd changer to the existing siemens head unit. He obtained a special patch lead which fits into the cd/radio back plug and then on to the cd changer. They did not touch any wiring. If there is a fault, it is there by the manufacturer - that is why I have been through this site...to try and obtain relative circuit diagrams to try and sort it out myself, instead of leaving the car at the dealer for ages....without them knowing exactly where to start.
thanks
I think I answered this post before
