Satellite Status If you have moved the StreetPilot several hundred miles since the last time it navigated using
satellite signals, you may find that the StreetPilot will calculate your location more quickly if you set the
approximate initial location.
To set the initial location:
1. From the Satellite Status page, press the OPTION key.
2. Highlight Set Initial Location and press the ENTER key.
3. Use the ROCKER keypad to point the panning arrow to your approximate area of the continent
(picture at right).
4. Press the ENTER key to select the location and begin searching for satellites.
