We have had the Magellan Roadmate for a year or so and it has had its share of software problems. We downloaded the latest map and version and when we entered propane on the hazmat, it did divert us around the tunnels in Maryland, however had us doing screwy things on the state roads in Virginia. We knew the route and did not follow the Magellan or it would have taken us around an extra hour to get where we were going. There is nothing like good old fashioned maps and logic.
