One thing I discovered when we were travelling this spring - if the wifi is not a secure network, you may not be able to update your route through Good Sam Maps. We were travelling with a Verizon hotspot, but once when I tried to update through open wifi, it wouldn't import. I fired up the hotspot and it worked, no problem. Something to be aware of. The dock will also automatically suggest that updates are available, and they seem to update frequently. I know on my Garmin, even with lifetime updates, it seems there's a limited number of times you can update.
