try reinstallation

This unit is designed for installation in cars, trucks, and vans with an existing radio opening. In many cases, a special
installation kit will be required to mount the radio to the dashboard. These kits are available at electronics supply stores
and car stereo specialist shops. Always check the kit application before purchasing to make sure the kit works with
your vehicle. If you need a kit but cannot find it available, call our toll-free “HELP” line at
1. Remove the detachable front panel if it is attached to the chassis by pushing the “Release” button. Slide the mounting
sleeve off of the chassis. If it is locked into position, use the removal tools (supplied) to disengage it.
2. Check the dashboard opening size by sliding the mounting sleeve into it. If the opening is not large enough, carefully
cut or file as necessary until the sleeve easily slides into the opening. Do not force the sleeve into the opening or
cause it to bend or bow. Check that there will be sufficient space behind the dashboard for the radio chassis.
3. Locate the series of bend tabs along the top, bottom, and sides of the mounting sleeve. With the sleeve fully inserted
into the dashboard opening, bend as many of the tabs outward as necessary so that the sleeve is firmly secured to
the dashboard.
4. Place the radio in front of the dashboard opening so that the wiring can be brought through the mounting sleeve.
Follow the wiring diagram carefully and make certain all connections of the wiring harness are secure and insulated
with wire nuts or electrical tape to insure proper operation of the unit. After completing the wiring connections, attach
the front panel and turn the unit on to confirm operation (ignition switch must be “on”). If unit does not operate, recheck
all wiring until problem is corrected. Once proper operation is achieved, turn off the ignition switch and proceed
with final mounting of the chassis.
5. Carefully slide the radio into the mounting sleeve making sure it is right-side-up until it is fully seated and the spring
clips lock it into place.
6. Attach one end of the perforated support strap (supplied) to the screw stud on the rear of the chassis using the hex
nut provided. Fasten the other end of the perforated strap to a secure part of the dashboard either above or below
the radio using the screw and hex nut provided. Bend the strap to position it as necessary.
CAUTION: The rear of the radio must be supported with the strap to prevent damage to the dashboard from the
weight of the radio or improper operation due to vibration.
7. Re-attach the front panel to the chassis and test radio operation by referring to the Operating Instructions for the unit.
1. If your vehicle requires the use of an installation kit to mount this radio, follow the instructions included with the
installation kit to attach the radio to the mounting plate supplied with the kit.
2. Wire and test the radio as described in Step 4 above.
3. Install the radio/mounting plate assembly to the sub-dashboard according to the instructions of the installation kit.
4. Attach the support strap to the radio and dashboard as described in Step 6 above.
5. Replace the dashboard trimpanel.

    Well, I don't know if it helps, but here are a few thoughts and hopefully they might give you ideas to diagnose the problem...

    1st possibility : there's an error in Michal's information. Although,
    it seems his setup is functional (I guess he wouldn't have posted
    photos with soldered cinch without testing it first) and for sure he
    cut the same wire as you did (the pictures are clear in that regard).
    Did you contact (PM) him ? Note : the fact that wire 10 connects to pin
    25 (SPDIF1) instead of 24 (SPDIF2) may be an error, but as you say, it
    doesn't matter : if you cut the wire from the CD, you shouldn't hear

    2nd possibility : your models are different revisions and the connector
    pin assignment has changed (would be surprising, but could explain the
    difference between your findings and Michal's regarding pin 24/25...)

    3rd possibility : a problem in your setup. Are you sure your switch (I
    guess you have a switch at the end of the wires soldered to connector
    pin10) is OK ? Isn't there a loose wire or something shorting wires
    together ?

    4th possibility : radiation ... WARNING !!!! : the following could
    damage the head unit if the pin layout is incorrect, and I'll take no
    responsability - YOU'VE BEEN WARNED :-) !!!! OK, you hear the CD
    playing when the wire is cut and hanging in the air in high impedance,
    but what if you ground it (via a resistor to reduce the risk) ?

    5th possibility : an error in Michal's setup that would connect his
    SPDIF source in parallel with (and not instead of) the internal CD, but
    if this external source has a much lower impedance, it could "master"
    the wire and "override" the internal CD's signal

    Finally, you could do your own reverse engineering independantly of Michal's :

    - do you have access to an oscilloscope ? This could give you a better
    understandng of what's on each pin of that cable. If not, maybe you
    have a device (amplifier, PC) with a SPDIF input... then you could try
    (!!!AGAIN : I TAKE NO RESPONSABLITY!!!) connecting it to the different
    pins of the cable too, and see if and where you're getting an SPDIF

    - at least, could you determine (with a multimeter) which pins are for power and ground ?

    - can you determine (with a multimeter again) if a pin from the cable's connector is wired for sure to either SPDIF1 of SPDIF2 ?

    - can you see on the CD player PCB what chip is responsible for producing SPDIF output and to which cable pin it's connected ?

    - as a last resort, you could do trial and error, and cut each wire in
    turn to see when music stops and if that gives a meaningful error...
    Maybe inserting a male/female connector with dip-switches in between
    would be the easiest to debug...

    Well, that's all for now. I can't promise I'll have time to come back
    anytime soon but hopefully some things above could help you go

Hi and welcome to FixYa,

One method of going about your concern is to look over the available records/documentations of the vehicle to ascertain the original dealer. You then would need to get in touch with this dealer armed with:

  • VIN;
  • proof of ownership;
  • model number and serial number of the radio/CD changer unit.
They in turn would look over their database to get the access/security code.

Some other methods that may or may not work are:
  • the security code is written/printed on the manual that originally came with the vehicle;
  • in a sticker or tape attached underneath/behind the ashtray, glove compartment or center console.
Perhaps you could post back the make & model of the vehicle and brand & model of the radio/CD changer.

Pls post back result(s). Good luck and Thank you for using FixYa.

Stereo flashing up PROTECTwill not let you access anything, had for 3 years and never inputted a key code or anything like that

you must have had the battery die or be disconnected for an extended period of time. this is a anti theft system. If you don't have the code, get the serial number off the back of the radio and call the manufacture.

Have a clarion cd player for the car recently bought off ebay, advertised with no code, but upon fitting the stereo, it keeps beeping at me, with no visible code display on the dash panel, please can you...

It is beeping because it requires a code

Unfortunately the only CLARION code available for free (using a serial number ) from anywhere on the Internet is if your radio also has a BARCODE SERIAL NUMBER beginning with C7000000 + + + + on a label somewhere on the metal casing.
(There are usually two barcodes on one label. The one required is the lower one )

If not then it will only be available from your Main Dealer or a Decoding Service or your local Car Radio / Audio Store who will connect a laptop to read/recode the memory chip (EEPROM)

Delco Car Radio

When battery power is removed and later applied to a
secured radio, the radio won’t turn on and LOC will
appear on the display.

Unlocking the Theft-Deterrent Feature After a
Power Loss
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition on. LOC will appear on the display.
2. Press MN and 000 will appear on the display.
3. Press MN again to make the last two digits agree
with your code.
4. Press HR to make the first one or two digits agree
with your code.
5. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show SEC, indicating the radio is
now operable and secure.
If you enter the wrong code eight times, INOP will
appear on the display. You will have to wait an hour with
the ignition on before you can try again. When you try
again, you will only have three chances to enter the
correct code before INOP appears.
If you lose or forget your code, contact your dealer.
Disabling the Theft-Deterrent Feature
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition to ACCESSORY or RUN.
2. Turn the radio off.
3. Press the 1 and 4 buttons together. Hold them down
until SEC shows on the display.
4. Press MN and 000 will appear on the display.
5. Press MN again to make the last two digits agree
with your code.
6. Press HR to make the first one or two digits agree
with your code.
7. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show ---, indicating that the radio
is no longer secured.
If the code entered is incorrect, SEC will appear on the
display. The radio will remain secured until the correct
code is entered.
Theft-Deterrent Feature (If Equipped)
THEFTLOCK is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power has been interrupted. If your battery loses power
for any reason, you must unlock the radio with the secret
code before it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
It is recommended that you read through all nine steps
before starting the procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time and
you must start the procedure over at Step 4.
1. Write down any three or four-digit number from
000 to 1999 and keep it in a safe place separate
from the vehicle.
2. Turn the ignition to ACCESSORY or RUN.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down
until --- shows on the display. Next you will use the
secret code number which you have written down.
5. Press MN and 000 will appear on the display.
6. Press MN again to make the last two digits agree
with your code.
7. Press HR to make the first one or two digits agree
with your code.
8. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show REP to let you know that you
need to repeat Steps 5 through 7 to confirm your
secret code.
9. Press AM-FM and this time the display will show
SEC to let you know that your radio is secure.
The LED indicator by the volume control will begin
flashing when the ignition is turned off.

Honda CRV Radio Code Error

My car (2005 Honda CRV) was shipped overseas and the radio asked for a code. After several tries, I searched the internet for a solution. Apparently Honda now allows you to obtain the code through their provided website. You will need the VIN #, the phone number and zip code that is on file when you purchased the car. Our car was purchased used and did not come with a manual. When I went to enter the code in I had already entered too many tries, now it reads ERROR E.

However, even before having the code (as well as now that it reads ERROR E) I can get the radio working. Push in preset buttons 1 and 6 and push in the power button simultaneously. A long number appears - at that point I pushed preset button 2 and the radio operated normally. Unfortunately, I do need to do this each time I turn the radio on.
