Perminate Live on Radio...

hello there, my girlfriends uncle has just bought a 206, and we recently changed the radio over to a after market cd player. however it seems that the radio isnt keeping its memory of what song was played last or radio stations. has anyone know what the peugeot wires do (i.e what colour does what?). many thanks

You will have 2 live wires going into the head unit. It's quite common for these to be the wrong way around.
You have 1 ignition feed (live when ignition is on)
And 1 permanant live (always live and saves memory)

Cut and swap over these 2 wires
