The new car I'm interested in does not have built-in navigation. I also don't own a cell-phone (and don't want to), so I can't display the phone's app on my cars 8 inch screen. Is it possible to buy a TomTom in-car navigation device ... connect it to my car, and have the navigation display show on my car's much larger screen? Cell-phone can do this, but can a gps device do this? Thanks.
