I'm pretty sure I've got one of those pieces of junk around somewhere. After using it and using an app on my android phone, I can't figure out how they sell anything or even remain in business. The app on the phone is so much more intuitive, easy to use and less expensive it's no contest for me. And that's besides the fact the brightness of the screen on GPS keeps going back to completely washed out instead of the higher contrast setting I keep resetting it to.
In general, GPS makers need to get their act together if they're ever going to sell me another one.
