You may find other uses as well such as when your hat blows off you head driving down the road.
To do this just name a waypoint from the number sequence.
These database waypoints are discussed in the chapter on databases. On most unit they must be no more than 6 characters long and contain no spaces but can contain any combination of letters and numbers and some punctuation.
The newest units permits 10 character names and these can include spaces.

They are often used to store intermediate turns and intersections that help define a route to a particular destination.
For example naming a waypoint to 001 explicitly will cause the next automatic number to be 002 unless this is in use.
It will automatically increment until it finds an empty number.
The waypoint screen from the G-12 family looks like: MARK POSITION ------------- Waypoint 001 . N 39 15.395' W121 02.166' - current position - not editable here.
------------- Add to route number __ - You can add a new waypoint to a route here. If you are standing still you can click 'average' on the waypoint save screen and the Garmin will start taking readings to average with the one that was captured when you hit the MARK key.
