Question about GPS
In order to determine your current location the GPS needs to receive telemetry information from several GPS satellites. In order to do that it needs a clear view of the sky. This should happen fairly quickly, typically within a few minutes, but depending on how and where you are operating the GPS the process could take significantly longer or the GPS might be unable to aquire a satellite lock at all.
Local geography such as mountains, hills, tall buildings and heavy forest can block the GPS's ability to receive satellite telemetry. The same thing can happen if you are trying to operate the unit indoors or inside of a vehicle without an external antenna. That's why most GPS receivers are installed on the dash board of the car: the windshield and side windows provide it the best view of the sky.
It is also possible that there is a problem with the GPS receiver or the antenna. To test it, try using the device outside in a relatively open area with a clear view of the sky in all directions. It should aquire a satellite fix in about five minutes or less.
