Looking to buy a newer Avic X910 for the 03' Tahoe that was stolen to re-build the system. I was considering putting the X series in my showtruck and moving my F90 to the tahoe. Is the bluetooth mic and wiring harness the same or would I need to re-wire it for the specific unit (ie can I just plug the x series into the f90 harness in my truck?)

I am sorry, I havent tryed that yet . I simply wanted to ask you a question. Is the bypass for the f90bt the same as the f900bt?

This answer goes for both of you, yes.
