Citroen Saxo CD Player will not play when engine running

I have a Citroen Saxo Forte 1.1 fitted with original CD/Radio player. When the engine is off, ignition key turned to battery power position, the CD Player recognises the CD and plays. When the engine is started it will not play the disc. If the engine is started before the disc is inserted it will not play and ejects disc. Does this sound like I need a new Radio/CD Unit or is this something more worrying? Any advice gratefully received. Thanks

    I have the same problem, but with a Citroen Dispatch CD Player. Very annoying. Not sure if I am best just replacing CD player, or if there is a way to fix the problem? Any help would be great! cheers

The car stereo has 2 +12V inputs: the constant batt input and the key in one.
So actually the stereo is always connected to +12V, even in standby.
When you turn your key, the key in input also starts, thus starting your stereo instantly.
When you turn the ignition on, the key in input is switched off for a couple of seconds, so that all the power goes to starting your engine.
After that key in input should be back on - this is your problem here.

One possible solution would be to cut this wire out, and split the RED battery +12V cable so that it enters in the key in input as well. Check wiring diagrams!.

Test this with cables out (without reinstalling the whole thing back in) and if it works.......leave it and put everything back in.

Only downside is, you have to turn off the radio by hand when you exit your car - or you could lose all battery power !

Can't save radio stations, have to tune the radio everytime I turn the car on. It doesnt work if you hold the numbers down. Can you help?


A common error wiring an after-market car stereo is where to connect the BATTERY and ACCESSORY wires. Under most conditions, these two wires do NOT get connected to the same point. The BATTERY wire connects to, well, the 12 volt positive terminal of the battery (or any 12 + volt source that is ALWAYS powered). This allows the radio clock to keep time and maintain the radio station presets when the vehicle is off / key is removed.

The ACCESSORY wire is connected to a point in the vehicle's electrical system that has 12 volts + whenever the ignition key is turned to the Run or Acessory position. When the key is NOT in these positions, the point should go from 12 volts + to 0. This change tells the radio to turn on or off, depending on the key position. The radio will power down when the key is removed, so you do not need to manually shut the radio off. This can save the battery if the radio volume was very low. The ONLY time you would accept both of these wires to be connected to the same point is when they are BOTH connected to the 12 volt + terminal of a battery (or wire that is always powered). If you wire this way, you will have to tune the power on and off each time you want to listen to the radio.

Check you manual for color or lable of these two wires, and place them as needed for the desired operation 1) Both on a constant 12 volt + source, or 2) BATT to a constant 12 volt + source and ACC to switched 12 volt + source.

I hope this helps. Please rate my reply with "4 thumbs up" if it did. Thanks!

Usually, purchase of a wiring harness designed specifically for your vehicle model and stereo solves this problem - as the required voltages and signals - including speakers - are made up and it is simply a "plug and play" operation. Newer cars will often require a "magic box" if you will, that uses some data signals in the car to turn on and off voltages for the stereo. Not installing the "magic box" will prevent much of the radio from working and can cause the loss of chimes, etc.

I am having trouble getting power to my new cd player. I have the orange battery wire hooked up, and also the ground wire is hooked up, and there is a red wire on the cd player that is a Ignition wire....


2 wires for power- one that is ALWAYS connected (remembers time, preset stations, etc.), and the other one you hook up to your ignition circuit (allows your radio to come on only when the key has been turned to ACC or RUN).

When you have wired this correctly, your radio will only come on when the ignition key is in ACC or RUN, and will ALSO remember the preset radio stations and the time, etc., when the key is turned off then back on again.

If you look at your fusebox, look for an ACC (accessory) junction that you can tap into. Also, don't forget that it's important to put a fuse in any wire you connect to a 12v+ source; don't rely on the fuse you are tapping into.

Hope this helps.

Hi the ignition wire needs constant power thats how it saves your memory. You will need a test light to find the wire that is constant power. With the key off touch the light tester to the power wires from the radio harness the one that turns the light on with the key off is the ignition wire and is to be connected to the ignition wire from the radio.

This is a safty feature of most factory car radios, if the power is turned off it thinks its being stolen so you need to put in a code which is normally unique to that radio. Most of the time the maker of the car will put the pin number in the car manual, but if your like me i dont have it anymore and found it was cheaper (and easier) to fit a new stereo.

Stop kenwood KDC-mp239 loosing radio settings with ignition off


You have two power leads bringing battery power into the radio. One is switched off when the ignition is off and the other power lead is always on. That second one is the one you may have wired wrong. You need to check that one out to make sure it stays on when the key is turned off. Good luck.

INTERMITTENT POWER PROBLEMS


Sounds like you have intermittent contact between the constant 12v and the ACC 12v power inputs. Remove the head unit, and make sure that the connections are properly insulated. (using inline **** connectors preferably)
