In a few weeks I'm leaving good ol' Indiana for an adventure around Seattle. We plan on hitting Mount Rainier, Olympic National Park, and seeing some sites around Seattle. I was hoping to input driving info, trail info, and important waypoints into my GPS before leaving home. However, I'm having trouble tracking down the info and how to put it into my unit.
Here's what I have at the moment: I have a Garmin Legend C. I have the Waypoint manager, but no additional Garmin maps. I have National Geographic Backroads Explorer. I also have a trails.com membership.
I'm guessing that using Google Earth or something like that I can probably track down waypoints for important things (like hotel, trail head, etc). How do I get driving directions and trail info into my unit?
