What makes you think the Camaro will have Nav as an option?
As far as I know, they don't even offer it in the Malibu...and that can come close to $30k when equipped.
If anything, we'll probably get blONdeStar like every other GM vehicle. Lame.

Keep the ugly button--I'll stick to Google Maps on my mobile phone.
(Really, something like the Trailblazer unit, or VW's new touch screen unit would be really REALLY nice, and definitely worthy of about $1800 as an option with an upgraded sound system).
