I didn't buy a video either.......spend an hour or so with the book.......then power the unit up and fool around with it a little........the next day, read the book again and you should be fine.......
The real key is to use it! The more you use the unit the easier it'll get......and the more comfortable you'll become.........you'll get to trust it instead of arguing with it!.
When you get out of your truck you are going to
mark that point by setting a
waypoint. At that time you can rename it if you want to.....the first way point will be 001 and I usually rename it to truck......
When you get ready to walk back to the truck you'll do a
Go To, and the unit will bring up a list of
waypoints after asking you if you want to find the
nearest waypoint or
waypoint by name. If you only have a few waypoints it really won't matter. There have been times when I've had quite a few and wanted the closest.....
The unit also keeps a track log so you could also do a track back if you wanted to go back the same way you came.....
Also, I don't use the pointer much, but find the map screen more useful.
If you want to cheat a little, I think you can download the instruction manual off Garmins website.......
I think you'll like it.......
