CG, I would talk to the dealer about the install and find out what parts they use to begin with and then go from there.. I knwo they have a NAV unit that will mount under a seat or something with info that ties into the Onstar system.. But I would start with the dealer or Hummer direct...

ZT,

Thanks for the advice but the dealers out here know very little other than how to take my money. Hehe!! Anyway, with all the vast knolage within this forum I am sure someone will have the answer sooner than later. BIG-C

CG,

Here are a couple of threads to take a look at:

Unfortunately, it looks like a pretty hopeless cause. GM is NOT interested in helping at all. Wiring appears to be different, and a custom reprogramming of the body computer would be needed. When I called Delphi, the lady told me they tried a retrofit, but the turn signals would no longer work on the test vehicle!
