I am trying to figure out which cluster I need, decided to go new. GM Parts - Genuine OEM GM Parts and Accessories Online My car is an 08 G6 Convertible 3.5. I already purchased a stereo JVC KW-M650BT. I know I will need a wiring harness and the steering wheel control. Just would rather change out cluster than have a box with screen that I have to figure where to put it.
