I just picked up my new Grand Touring last night. When I tried to play with the navigation system, I get a message telling me this vehicle doesn't come with a navigation system. Doesn't the Grand Touring trim level come with that? That's why I bought it and not the middle touring version. I know you can ADD it to the Touring version, but I didn't realize you had to pay extra to add it to the Grand Touring, too. Why does the window sticker say "Navigation System: No Charge?" Any help would be appreciated.
