About Satellite Signals
Your c510 must acquire satellite signals
to operate. If you are indoors, near tall
buildings or trees, or in a parking garage,
the c510 cannot acquire satellites.
Go outside to an area free from tall
obstructions to use your c510. When the
c510 has acquired satellite signals, the
signal strength bars on the Menu page
are green . When it loses satellite
signals, the bars turn red or disappear
. For more information about GPS,
visit www.garmin.com/aboutGPS.
Charging the c510
To charge the c510, connect the power
cable to the c510 and a power source.
Calibrating the Screen
