I live on Long Island, About 100 miles from Manhattan. This should be a hot satellite zone. While traveling to an address I constantly receive the navigation data loss warning. I also get the 'searching for driving directions' pop up which most times never goes away and makes the navigation app useless.. If I'm moving and enter an address for driving directions it never seems to lock in and I get the 2 mentioned warnings above. Is navigation on the Vtab broken? Or do I need a different app.
