About GPS Satellite
Signals
Your PND must acquire GPS (Global
Positioning System) satellite signals to
navigate. If you are indoors, near tall
buildings or trees, or in a parking garage,
your PND cannot acquire satellites.
Go outside to an area free from tall
obstructions to use your PND.
When your PND has acquired satellite
signals, the signal strength bars on the
Menu page are green . When it
loses satellite signals, the bars turn red or
clear .
For more information about GPS, go to
www.garmin.com/aboutGPS.
Caring for Your PND
Your PND contains sensitive electronic
components that can be permanently
damaged if exposed to excessive shock
or vibration. To minimize the risk of
damage to your PND, avoid dropping
your unit and operating it in high-shock
and high-vibration environments.
Cleaning the Unit
The PND is constructed of high-quality
materials and does not require user
maintenance other than cleaning. Clean
the unit’s outer casing (not the touch
screen) using a cloth dampened with
a mild detergent solution, and then
wipe dry. Avoid chemical cleaners
and solvents that can damage plastic
components.
