GPSInformation has reviewed the Magellan Roadmate 800 and report:
Overall this is a good autorouting product and provides an easy to use navigation screen with good attention to user interface features. The guidance was good but added extra messages that could get you in trouble. I found the autorouter was fast and it did a pretty good job most of the time.
The GPS was very sensitive and locked quickly. The included mp3 player was disappointing in that it could not be used while navigating.
