It will work with no issues as long as the PDIM in the kit is one of the newer ones. You'll also need to get the radio reflashed by the dealer so it will recognize the PDIM.
Your best bet is to talk to Gene Culley at GM Parts Warehouse. His number is in his signature about twenty posts back from here.
Thank you for the referral. We can basically make you up a PDIM kit using the latest and greatest PDIM. Feel free to send me an email or give me a call.
