Love my Nuvi but have a reoccuring problem. When I connect it via USB, it will cycle sometimes 20x before making a connection with computer. I then upload a .gpx file and disconnect. Then after turning back it on, it will boot up to the loading maps page and then turn off. I cycle power 10-20x before it finally comes up. The software version is 2.30 and the gps firmware is 2.70. Any help appreciated.
