Does anyone know who provides the maps for the Z1? Maybe it's just my area (Long Island, NY), but I'm constantly getting lost with this thing. And it's downright embarrasing when I have other people in the car, not to mention scarey when I'm down a dead end street in the middle of the night and the map tells me to go straight ahead! I'd hate to have to carry my little Magellan Roadmate portable with me. It's always right!
