No maps, error installing maps on Garmin DriveSmart 61

I've had a Garmin DriveSmart for a few years. I tried to update the maps and there was a hiccup during the process. Ever since then, Garmin Express says the maps are up to date but the Garmin says no maps are installed. Sometimes on startup it says that the maps are corrupt.

I've tried a couple times telling Garmin Express to reinstall the maps. The result is the error, "There was an error installing the update".

In the Garmin's Setup/Reset menu, I've tried both "Reset Default Settings", and "Delete Data and Reset Settings" The latter says that it doesn't delete the maps.

The map update worked fine for this unit for a previous map. I've had no problems with three other Garmin units (different models).

Any suggestions?

 

Thanks Nuvi-Nebie, I installed Basecamp with MapInstall and tried that--twice. Both times MapInstall goes through a long process to send the map, build indices, etc. But at the very end MapInstall says this:

Map not transferred to "Garmin DriveSmart 61"
The data was not successfully sent.

(Emphasis mine.)

I think the problem might be that the Garmin is timing out and turning off during the process. FWIW Basecamp stops showing it when that happens.

Is there way I can make the Garmin stay on throughout the process? When I see that it has turned off, would it make sense to unplug it and plug it back in to try to get it to turn back on?

 

Thanks, that fixed it. Woo-hoo!
