I just got back from Circuit City after having a new CD deck put in my Trailblazer. Before they started they said "when we hook this up you wont have lock etc. chime anymore and your oil life monitor wont work either." I was like that stuff is in my radio? Man they couldnt put just two more functions in the BCM??!! The guy said when they started coming out with these newer Delphi radios some cars even had the air bags hooked up to them. So stupid. Now the passenger rear window wont roll up from my driver control, I'll have to take it back because the install probably caused it. They had to do some wiring in one of my fuse boxes :blink: .
