the problem is how do I know what isn't correct? From what I've learned the map update didn't finish properly. So that sent me into a bootup repeat cycle.
Exploring the nuvi I don't see anything that show ups as maps or the like in the directory tree.
There's likely a lot of hidden files but I didn't explore quite that far.
Just hoping if I restore the standard firmware I don't go back to the never ending reboot.
