I have a very a temperamental GPS link. Sometimes it obtains satellite lock quickly, and other times it just sits on the "Searching for GPS..." message forever. I'll be on the streets with no obstructions and it still does not lock onto a GPS in a reasonable time. My Garmin Nuvi will always obtain a lock in about 30 seconds. Sometimes I try reboot and then GPS does obtain lock, but it would royally suck if I had to do this every time I have a slow GPS link. Does anyone else experience this? Is there a fix?
