Summary: I thought this unit was really good, until I went to Calgary this past week. Updated maps 2 weeks ago. Took 1/1/2 hrs. for a 30 minute drive from the airport because the unit took me round and round and through downtown. Put in another address and it wanted to take me to a city in BC.
Summary: Product failed out of the box. System is locked in GPS Simulation mode which prevents it from acquiring satilites. (this renders the unit useless). Updated software and did a hard reset which did not fix the problem. According to several websites, this is a common issue with Garmin.
