I’m going to assume that it’s the same as for our “guest” GPSr, which is a GPS72 (minus the Map).
I think your problem is that your assuming that like some other Garmin models you can delete the waypoints in mass from the [Goto] button’s screen(s). This is NOT the case, with the 72.
From a “normal” screen, press [Menu], then [Menu] again … then scroll down to “Points” (short for Waypoints), and hit [enter] … then select “Waypoints” and hit [enter]. Now lets stop for a second … I bet your thinking that your at the exact same screen you’d have been if you had started out with the [Goto] button … but your not … your at a more advanced version screen. So now from this screen (which should be showing all your waypoints), press the [Menu] key … you should now see the choices of deleting a single waypoint, or all waypoints, or waypoints of a specific symbol type.
