just a joke man. I only have little knowledge of Coastal from reading mixed opinions online. I've also saw the YourGm site and thought "Wow, that's cheap" but also wondered "why?"
Maybe they are the same and simple using an old business strategy to get all the customers??(those that will pay whatever & those looking for a deal)
I'm not sure. But I think I may have seen the YourGM person as a member of one of the GM truck forums.
and ED, if they new 2009 Nav DVD lets you turn off the restrictions like the guys have stated, the only limit from then will be watching DVD's on the front screen while moving. The prices might drop even more. Check out
