The past few months, when I use VZ Navigator, the phone often gives an error message that the start point is not near a roadway, when in fact, I can be on the shoulder of a major interstate. It has lately taken to restarting the phone anywhere from 1 to 5 miles from the destination. Is there some sort of update that I missed, a software glitch, or any ideas? Being a truck driver delivering to some off the wall places, this gets to be a little frustrating. Set up for truck routing, the routing usually isn't too bad....When it calculates. Might the truck setting be the problem?
