Hi all, yes I know this post is a bit off topic - BUT - I realise how knowledgeable you all are on her, and 'HOPE' someone may be able to help - or point me in the right direction, so here goes: I have a friend who works for me who has just bought a 1998 Vauxhall Vectra (yuk - told him to buy my old V8110), and he needs to know how to locate the wire on the back of the factory fit radio/cassette unit that is used for the 'telephone mute' function. Radio fitted is a 400/4664 unit - with another number on it (GM400V1638220). Can anyone assist, please?
Regards, Dave
