I think I will be giving my unit back to BestBuy - the nav feature added some big $$$ to the cost, and it works so poorly that it seems wasteful to keep it. My iPhone's free google maps app does a better job of displaying street names! What could possible be the root cause for such a poor user experience?
Totally agree & can't believe I have the unit still. Had someone in my car the other day & they couldn't believe it when we passed a street we were looking for. They have a generic unit & even it has the major streets & such when not in navi mode. It's really sad being how much this damn thing cost.
