Has anyone put an aftermarket Head Unit in the SKY? For the price of the premium sound system, I figure I could put something much nicer in. Also want to put something with NAV in. My only concern is, would scrap the onstar phone features?
I agree with you that your money would be better spent on a nicer after market system. But like you said what about the use of on star is it completely lost and how many electrical parts waranty's will be voided if you upgrade.
