Is this supported yet?
I don't think 07 models are supported yet. I didn't have any luck getting FS to connect to an 07 Suburban. According to Ross, GM made another change. They're working on an update so FS will connect. Ross can supply a definitive answer.

AFAIK, '07 and up is all different... I'm hoping V2 will support 'em too - I'll be able to tune all 3 of my vehicles with it if it does! w00t!
