Hi
I hope somebody can help me.
I have bought a replacement radio/CD/MP3 for my car but it will not hold

the

memory for stations or sound settings.
The plug on the back is an ISO type. The car is a Citroen C5. Can anybody
tell me which wire from the car loom needs to connect to the memory wire

for

the radio please.
Many thanks for any help.
Mike


There is usually a sticker on the head unit that tells you what pin is what.
Just swap the two power leads over. Possibly red / white and red / black.



You'll be bloody lucky on a Citroen!! The theory is fine, but I'd
almost bet money that all the wires are the same colour. You'll need
some detail from Citroen or the radio manf may have a help line...
