I downloaded the free version and found that the map is not moving as I move. The arrow does, but once it hits the edge of the phone it disappears. I"ll have to check the settings and see if it's something I missed. I'll try it for a while and keep it as a backup. May spring for a zumo with permanent power source as I love to use GPS while riding. Not only do I not get lost, but it helps me plan my approached for turns by seeing which way the road goes.

Greatly appreciate all the responses....that's what makes this forum so great!
