Hello everybody, I will be working with Sky Auto Vision (AuCar) for a group buy on some head units. I can save you guys $200 on 5-10 units and $250 on 10+ units. There are 3 models , Black and silver, Piano black, and Carbon Fiber. The carbon fiber is $100 more than the other 2 models. I am attatching my link to the Demo video so everybody can see it. It is awesome!! Sounds amazing!! I just want to get some feedback. Also there is a link in my youtube video comments with more information and shows the regular retail price in that link. Thanks so much.
