GPS Tips While the receiver is gathering information, your location on the map can show as different from where you actually are located. Be patient; as soon as the receiver gathers enough satellite information, your proper location is shown on the map. Any time you have traveled more than 600 miles with the GPS receiver turned off, the receiver can take longer than normal to initialize and find your location. The GPS receiver can lose satellite signals due to interference from such items as buildings, tunnels, and heavy tree cover. Monitoring the GPS status is recommended.
