I have a few different Garmin GPS units. I also have at least 1500 waypoints saved and they all don't go onto each Garmin unit I have.
Depending on use, I'll have some waypoints on one unit and other waypoints on another unit.
Now can you imagine what its like going through well over 1500 waypoints to pick the ones I want.
That is why I'd like to have waypoint folders to pick from. That was never an issue when I used MapSource.
