Help with installing a nokia ck-7 car kit

[j6onn]

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???

Normally most members on here use the SOT122s adaptor cables/connector

If you look behind the radio in behind the glove compartment there are wires labeled up already. If you have a latest blackberry phone with latest software it will no work with this kit.
