I have a trouble report in to Garmin about the lack of a User Manual for Mobile PC. They are looking into it. It might help to speed things along if others would email or phone and complain, too. Their suggestion in the meantime is to look at the Help system in Mobile PC. You've probably already discovered that it's of minimal help.
The other option is to take a look through the
Mobile XT Users Manual. It's far from perfect but it's a whole lot better than the other options.
