I have a 2011 Silverado with Bluetooth. My S3 works great with it but it doesn't have Bluetooth audio capabilities. I was wondering if anyone was aware of an app that would play music via bluetooth. I was hoping there would be something out there that would work. It plays my voice guided navigation so I was assuming there would be a way to make it play my music? Eventually I am going to get a Pioneer Head Unit but I was hoping for a temporary fix.
