It’s no secret that the manuals many GPS makers puts out with their handheld GPS units aren’t always ideal. They can be very confusing, give cursory explanations of more complicated functions, and often leave out any mention at all of advanced functions. Plus, as firmware gets updated and features get added/dropped, the printed versions become out-of-date, and even the online PDF versions lag in adding descriptions of new features. Here are some online resources to help plug the info gaps for these units.
