Hi, 673king, My Garmin is c330, but I think that all GPS's of this nature are programmed only for roads -- not bodies of water. I haven't updated my 2-yr.-old-Garmin yet for new maps, but what you describe concerning the red question mark is exactly what I get when I am on a road that was constructed after my Garmin was programmed. Since the GPS can't find the road in its memory, it merely has a red question mark until I get onto a road that the software recognizes. It then operates as usual.

I sat on the phone for 30 minutes waiting for Garmin support when my Nuvi suddenly had no touch screen response. They had me delete a file on the device (with it hooked to my computer) then reboot and it went thru a touch screen alignment and it worked.
Sadly, it has frozen again and I don't recall the file (it had been a GCD file in all caps, that is all I know and I don't see a file in all caps any more). I will be calling support tomorrow.
My take is that it *is* a firmware thing *and* there is some way to reset the firmware.
