Hello peeps, can someone please help? Im going to install a nokia ck-7 hands free kit through my cdr 2005 and im unsure which wires i need to splice into so i can use the mute function and have the calls through the car speakers. Someone has said i need to connect the mute to pin 13 and then the audio+ into pin 16 and audio neg into pin 19. Also someone put a diagram on here showing the correct pins as c3,a3 and c8 which has confused me a little??? Also am i right to cut the lead from the external speaker and use as audio in???
