Hi, can anyone help me, i am about to fit a kenwood dnx 5240 into a 06 plate b7 with the concert stereo fitted, i have all the parts needed just a bit lost on the concert radio, does anyone know what the small yellowey mustard type colour wire in the center of the back of the radio is and also does anyone know which wire in the audi loom is the mute wire for the phone, i have fitted a similar system to my own a4 b6 but as it was not the bluetooth version i didn't need this function.
Thanks in advance,
Matt
