Do any of you have tried these maps on other nuvi series gps?
I really need this maps installed and working correctly.

Thanks
I installed the maps on my 3790T a few months ago. I've not encountered any of the problems you describe. Did you install the maps on a memory card? It may be your microSD or the version of maps you installed.

I do notice that when using my microSD, every two weeks or so, the maps "slow down" or freeze but Nuvi just restarts/reboots itself. But I attribute that to me leaving Nuvi in standby instead of turning it completely off.
