Hi, I've got a Nuvi 200. Meddling with it and stumbled upon a secret cave??Get to your odometre page and press the odometre for about 5 secs. A different module pops up.In it are the the shutdown page, logging control page(tracking capability???), stack page, TSK Mem Statistics, Nonvol info, Message Banners.What the hell are these? No mention in the manual.
