Re: mobile phone car kit
I installed mine this weekend. There are three sockets hanging behind the fuse box on the drivers side. Two are white, and one is blue. You are going to use the two-pin white, and the four-pin blue.
The two-pin white is an input for the head unit that takes the speaker output from your handsfree kit, and relays it out of the audio system speakers, with you able to control the volume.
The blue four-pin provides 12v, 12v acc, Gnd and Mute.
The pin config is as follows:
Looking into the blue socket (With the factory cables coming out of the back, away from you), A = 12v, B = GND, C = 12v Acc, D = Mute.
