There are two Bluetooth modules in the Camaro. One for hands free cell phone use and another for streaming music to the radio.
1. Hands free cell phone - You need to replace the Onstar module in the Camaro with a Bluetooth enabled Onstar module
2. Music streaming - You can purchase/install the PDIM accessory kit which will also give you a USB port to connect an MP3 device such as an iPod or USB thumb drive
