Just an update on the Magellan Roadmate 760.
First off, I knew the internal maps were outdated. They are about 2 years old and apparently were a little outdated then a major interstate around Richmond is not on the maps.
Additionally new exchanges around Wash. DC, which have many new roads and closed some existing roads are not in the maps. The maps I believe are from Nav-Tec.
Magellan says the maps are scheduled to be updated in Nov or Dec this year.
But it does work as advertised. It provides voice communication to the driver about upcoming turns, starting about 1.5 miles away. Then down to .4 or .5 tenths of a mile and then "turn right (or left)" on such and such street name. If you miss a turn it provides automatic route recalculation.
So I'm pleased with it!
