My buddy has an 06 GP I believe it's just a plain GT, and long story short his BCM got shorted out. Can he get a used BCM and run it, say from another 06 GP or are they programmed specific for each car?
You'll probably have to get it programmed at a dealer. Very few others can do it. I've never tried it on a GP, but never had a used one work yet without a program.
