You only get onstar free for one year and I believe the turn by turn nav is a separate cost from the reg onstar. not sure if anyone researched it but it was mentioned in earlier posts that onstar was teaming up w/mapquest for the turn by turn. dont know bout you but many people expressed the dislike of mapquest because they give wrong directions. i can personally say that mapquest sucks and they are behind the times of updating their information. Plus w/the blind spots behind the vehicle w/o the nav system you will not have the back up camera.bug2323 said:
