This has something to do with Windows and the Nuvi itself. When you erase a file, you need to wait a little while longer after the box with the horizontal bar which indicates the file being erased goes off ( wait about 10 sec ). It seems that when you exit immediately after the box goes off and you do something else, Windows is not done and aborts the erase, thus leaving the file intact.
Try this and see if it fix the problem on your Nuvi
Still no luck. The files are still there.
Have you tried switching off the pre-installed maps ??
I believe it will switch on by itself.
I took an ride with my 3790 last night, if your destination takes more than 30 min, the unit shuts down by itself. Any destination less than 10min is okay.
I think it's the heat that contribute to the shutdown.
