Alex is right and I can account for that. You are actually doing an exact retrofit as Alex did with his car. If I remember correctly you'd have to gather a mic wiring to your fzd unit as well for the mic to work. Now why not just use one of the modules only since you are looking to add only Bluetooth functionality. Kind of redundant to have both modules when one can do the same. Not that they can't coexist in the same car but your gonna have to do a lot of reconnecting and figuring where wires go. Is the car pre-wired for a TCU ie the SA640 prep option?
