hi guys, have just bought this stereo, its secondhand so came with no box or instructions so im a bit baffled, it is a blaupunkt mp68. has all wires connected and a blue parrot box. which says on it "universal radio mute" i have no idea what this is?
if you look at the pictures youll see another slot at the back of this which i have no connector for. what is it and where can i get one?
also youll see ive pointed out for wires, red, black, brown and white which are labelled line"-" or line"+". where do these go?
and finally theres a blue and yellow wire which you can see in the picture with bullet connectors on. the yellow on is labelled "mute in 2" but nothing on the blue, any helps guys. thanks
