GPS or smart phone
I was wondering what was the difference between a GPS app on a smartphone and the GPS units such as Garmin? We expect to use it to RV travel.

The smart phone won't work everywhere, that's the downside. The smart phone only works where there is cell service or wi fi. The gps, satellite based, works everywhere. The smart phone is of no use in huge parts of Death Valley for instance. We have both, but use the GPS most of the time when on the road.
