damn i better get it checked out by the dealer...read online, it could be the alternator or the aux water pump...

Now the NAV is being a pain...sometimes it works sometimes it doesnt.
This morning...driving to work...listening to radio and while sitting in traffic, tried to turn on the NAV...but it says please wait a moment...never comes on. Did i do something wrong? i turned the car off....started it again, same thing...ideas?
