The other night I was playing around with my map source with Topo. I got an idea to see if I could transfer one or two sections of my Topo to my old eTrex Legend and it worked. Now my question is how do I delete them off the unit?
Thanks,
Robert
Anytime you send a new batch of maps to that unit, it will replace the installed maps. There's no need to delete any maps, the software will take care of it for you next time you load up. If you don't want them to display in the meantime, you can disable them in the map setup. If you must dust them from the unit, just send any type of map, such as the Garmin US tide station map:
