GPS Tips
While the receiver is gathering information, your location on the
map might appear different from where you are actually located.
As soon as the receiver gathers enough satellite information, your
proper location appears on the map.
Any time you have traveled more than 600 miles with the GPS
receiver turned off, the receiver might take longer than normal to
initialize and nd 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.
