This has started happening over the last week or so ... when I start driving, all map portions near where I started are fine, but after I drive about 5 km, I drive past the edge of the earth apparently. New map segments to not appear on the nav screen, and the "known" map eventually scrolls off, and I find myself in the middle of nothingness. I've been at 5.9 (94) since end of March, no recent f/w upgrades. I've reset the screen twice, but no improvement. If I stop moving, map portions for the new area start popping in. I'm figuring there's something funny with my 3G connection and map updates is just the most obvious manifestation. There has also been the odd, random stop to internet radio feed as well.
