I need some help. I have an 04 QC that came witht he RAZ head unit and Infinity speakers. I replaced it with the RB1 and added a Motorola OEM bluetooth hands free system for the Motorola 710 phone. Here is my question. The Motorola system needs to connect to the MUTE wire of the radio (tomute the sytem for incoming/outgoing calls). Which wire on the 22 pin plug is the mute wire? I would like to know the color of the wire as well if possible to make sure I tap into the right one. The RB1 does not indicate what wire does what. If this is part of another thread I apologize, I have been searching and cannot find the information. Thanks! :help:
