The Legend H is my very first GPS receiver. If this is your situation, be prepared to spend quite a bit of time online or in the library to learn how to use this device, because the Garmin-supplied "manual" isn't worth the paper it's on is printed. And don't look for help on the Garmin website. Quick example: Legend H is WAAS compatible, so of course you need to enable WAAS. But if your legend doesn't see either of the two WAAS satellites (mine does not yet) the accuracy of your legend will be reduced. The manual doesn't mention this; no index entry for WAAS.
