I know I'll probably get a back-lash here, but I've had the same Tom-Tom now for about 8 or 9 years. We do the map uploads once a year, and other than taking you down a road that turns out to be flooded (we laughed about that for a couple years), it's still dependable, reliable, and by far the easiest and the best we've used. Used with a paper map, you can't beat it! Now Google maps comes in right on par with Tom-Tom, but ... I-phone Google Maps also costs bandwidth data on your phone. Not such a good deal when you use your phone a lot. Tom-Tom is still our best, going strong after all these years, and we use as recently as yesterday coming home Sunday afternoon after camping the week-end.
Stick with old stand-by's and forget new-age technology and gizmos that are designed to break down after a year so you have to buy a new one! Dig that Tom-Tom out of the closet and plug it in!
