Title: Don't throw away your paper maps!
Review: I bought this in July 2007 for a trip from Wisconsin west to Yellowstone and Glacier. It failed to do its primary job - consistently getting us to where we wanted to go. Sometimes it did and sometimes it didn't. There were times when we chose a listed POI, saw signs to it, and followed the signs instead of the Mio, which was telling us to go somewhere else. When we got to the POI, the Mio still didn't know it, and kept telling us to go elsewhere. This was not an isolated incident, and I've had similar problems in Wisconsin. I haven't tried to use it for the past few months. I can understand it taking you on a less efficient route occasionally, but if you can't be sure you'll really end up where you want to go, what good is it?
