    If it's the same part number then yes it should work. If it's a different part number then no it will probably not work. Check GMPARTSDIRECT.com for part numbers.

    Unfortunately not. I've seen that module and the cellular antenna connector is different from the CTS module.

    This is freakin' ridiculous that I can't take my car back to the dealer, pay for a new module and have them install it!!

    I would suggest checking ebay everyday. I'm certain they are out there bur sell immediately. Knowing how easy the mod was and the benefit to doing it, I would pay $500 for one if I had to. That being said, I'm sure they don't last long!

    I'll keep my eyes/ears open.

    thanks matt... for the reply. This thread has been running a while and wasn't sure how much interest there was in it anymore. Not sure if I am willing to drop $500 on one but, then again i am not having much luck finding one.

    I do have a call in to my brother in-law who owns a body shop, thinking he may be able to order the part or have a connection to locate one.

    $420 is totally worth it. It's the single most cost-effective mod I've ever done (then again, it's illegal to talk on the phone while driving in California). I will never buy a car without BT after this!

    The base 2010 CTS doesn't have BT either.

    Has anybody found a source for these 8.1 modules? I've been eBaying for a while with no luck.
