Has anyone successfully found a way to update the bluetooth?  My 5G phone is having difficulties but my old 4G was fine.  After some internet research, it seems as if I need the latest version of bluetooth?  When I called a local dealer, he laughed and said I needed a new vehicle.

Same issue with my '05.  Dreading on interacting with a dealer for a fix.  Can a regular mechanic handle this?  One wanted to take out the air suspension and replace it with springs.  Anyone know if this works?
