I went on a trip this weekend and was using the gps on my dx, or should i say trying to. I knew where the town was i was really using it to tell me how far i had left and when i got there how to get to the exact location. But it went nuts when i turned it on. For over an hour it kept saying "searching for signal" i tried turning it off and back on, updating my roaming and everything. I made sure i had my gps settings on(all of them). Finally after i quit messing w it bout 30 mins latter it worked. Is this a known problem? Any fixes?
