02Avalanche, for the Audio Controls on the 02's, you'd have to go out of your way and possibly break something to accidentally change the station. The controls are set back almost even with the back of the airbag unit. If you want to change something, you have to aim for it.
You'd like them.
I haven't even started looking into putting an 03 wheel and controls on the 02's. First off, the wheel with all the buttons is going to run about $350-$500, the airbag is going to run you another $200-$300. Then making a custom harness to work with the 02's. Okay, there will be a few people out there willing to shell out that kind of doah for audio controls, but for that price, you could get a pretty nice stereo upgrade.
Plus, the other functions are most likely not going to work (A/C, OnStar, Trip Computer functions, etc.)
I love the new wheel and controls, but putting all that in previous design? It would be like putting a CDRW in a 386 computer.
Still want to look into it though.
