I have a Garmin Venture CX.
My gps is full and won't allow me to enter any new waypoints. I'd like to delete a large number of the ones I already have loaded (especially from other states I don't plan on visiting for awhile), however, the Garmin instruction book only details how to delete the waypoints one at a time. This is time consuming and I'm wondering:
1) Is there a way to delete more than one way point at a time, like when you delete multiple pics from a digital camera?
2) Is there a waypoint managing software program that can go in and clear these out?
or
3) I have a SD Card installed, which I think only stores maps for me (though I don't have any installed). Can it be used to store additional waypoints so I don't need to delete as many?
Thanks for your help.
