My CD player stays on after I turn the ignition out. Which means I have to hold the power off button down for it to go off. So is it a case of switichng some wires around? but anyone know which one(s)?

look at the back of the head unit
there will be a red and yellow one
try swaping them round???

Have you got the positive fed directly to the battery??

If so, you may want to take a positive feed that switches off when the car is turned off, i.e. ciggie lighter.

I am no expert and may be wrong here but marcrs, matt, richaresty etc etc may jump in and advise better.

I think Lew is right, there should be a red wire and a yellow wire, one will be connected together with a covered bullet connector and the other will have a blank on the end of the bullet connector, the one thats blanked needs connecting and the one thats connected needs blanking, i think thats how mine was anyway

I just got a new head unit from santa with all the iso wiring diagrams in the box so if you need any more pics up I can get them for you.

The red and yellow wires are the most common fault though. Try option 1 first then 2. Option 3 as you can see (top right) is a "phenomenon" :lol:

that usually only happens in Audi's and Volkswagen's.

if swapping the red and yellow wires over doesnt sort the problem you will have to run a switch live from the ciggy lighter to the red wire on the ISO.

basically just feeds power to the head unit when the ignition is on.

need any more help let me know and i'll go into it in detail as do this all the time at work (halfords audio fitter see :lol:
