installing "extra" maps on 3760t

 

I'm having issues trying to install extra maps, like topos on my nuvi 3760t.
I download the map, double click it, it installs in the mapinstall program, and I install it on my nuvi.
then when i restart my nuvi, i get a "can't unlock map" error. and the maps are not visible in the list of maps.

garmin support docs say if you get the c"an't unlock error", to remove the gmapsupp.img file, but that's the file that has the newly installed map in it, no?

any suggestions?

I did. that's what's

I did.

that's what's maddening about it all.

got the maps from the topo site, "installed them into MapSource, used MapSource to install them on the nuvi.

after that, got the "can't unlock message."

oh wait... I used MapInstall from Garmin. MapSource appears to be Windows only!

is that the issue?

Yes.

Are you saving that you are using a Mac?

If so, then get Garmin's BaseCamp software and try that.

And it's free
