Does anyone know anything about the Bluetooth in an 09 Traverse? My sister in law has an 09 LT1. I guess LT2s had Bluetooth. Since Illinois just banned handheld phone use, she'd like to have integrated Bluetooth. Do you know which box part numbers would work, and if it would be plug and play as far as Bluetooth functionality would be concerned? Don't know if she has active OnStar or if she wants to keep it. Though, she may want to due audio streaming also. I don't know much about the Bluetooth options out there. Is there a good aftermarket option that has OEM style integration that is more capable?
