Ben...for the Nuvi non-op issue you mentioned...you might try the Maint start-up...
with the Nuvi OFF,
hold your finger in the upper, LH corner of the screen while turning the Nuvi on,
continue to hold your finger to the screen until the Maint screen comes on - if it will come on at all, that is, in your case...if it doesn't come on, you'll probably have to send it in for a factory repair, etc.
This method of start-up, among other thins, will allow you to erase ALL your FAVORITE waypoints at one time - if you have a bunch you want to get rid of, perhaps - you can duplicate them in a PC file if you use EasyGPS.com (and your GPS-PC accessory cable) before deleting in your NUVI, for a back up.
I'm having a problem in that I can't load the POI sofware from Garmin due to some glitch (%APPDATA%) in my PC that I haven't found a cure for, yet...any help out there for this one? The darn MS site has a 'workaround' for the %APPDATA% error problems, but of course their instructions for Vista don't match what's on my Vista window - A curse on you, Microsoft!
