Quick tutorial on the difference between a track & route.
A track or tracklog is a breadcrumb trail of your current activity on your GPS. This could be your day of hiking in a park. You can use the tracback feature on your garmin gpsmap 62 to navigate back using the same track if you are unable to follow the trail.
You can also save the track for future use.
Routes are a little different. Typically they contain less points than your trackfile. So in our example of hiking, we want to save only the trails we hiked to send to our friend or use at a later time.
We can edit the track file in Basecamp, split a single track into 2 or more segments. From there we can save each track as a route. From here, we can save each new route under a new name and send it back to the GPS.
From there, you can navigate the route by using the FIND | ROUTES menu and navigate just like a track. For simplicity, you could also further edit the route so that it only contains the single path and use the reverse route feature to navigate back. Useful for out & back trails.
