I have successfully uploaded a “mymap” to my Garmin GPS. If I would want to erase it from my GPS, how should I proceed? The same, if I wish to update it, how to I proceed?
Thanks for helping.
However, I’m not sure to understand well. I have a Garmin Nüvi 250W. I don’t find where to “push menu twice”. Maybe then it depends on the version of Garmin unit.
The waypoints that I have transferred with TakItWithMe have all been placed in my “favorites”, and their corresponding names well appear on the map.
I haven’t found a way to delete waypoints, except one at the time.
My other question is also, if I update either a “Mymaps” set of waypoints or a “Google Earth” set of waypoints, will this update the set of waypoints already put on my GPS, that is add the new waypoints to the existing set, or will it put a second copy of each waypoint already on my GPS? I haven’t dared experimenting it, due to the fact that, in any event, I would have to erase all waypoint one by one!…
I don’t have a Nuvi so I’m not sure if they support an ‘erase all’ method.
On the GPSMAP Garmin series, if you recopy a waypoint with the exact same name as one in memory, it will overwrite the old one. This allowed for fairly easy updates.
You could try this with a couple of waypoint in Google Earth to see what the Nuvi does.
