Hi everyone, I have searched the forum for answers to my questions, but am still a little confused. Hopefully, someone might have some answers. I am hoping to install the Z120 into an 07' Chevy Tahoe LTZ w/Bose speakers. (1) Will the Bose speakers still work with the pioneer unit? (2) XM Radio was factory installed with the car. Is this factory XM radio compatible with the Avic-Z120? Thanks for your help!
