Welcome to the forum,
This forum is full of great looking trucks; packed with great mod ideas and there are loads of knowledgeable and experienced people here.
I would complain about this to the dealer so they can get it in the 'system'. If you have lived there for 7 years, I think it is their responsibility to get the map upgraded at no cost. If you get a hold of the GPS provider, they will charge you for any updates....whether or not they have your area.
AND - We all like pix! Got any to share?
Enjoy the Z!
