About GPS Satellite
Signals
Your nüvi must acquire GPS
(Global Positioning System) satellite
signals in order to navigate. If you
are indoors, near tall buildings or
trees, or in a parking garage, your
nüvi may not acquire satellites. Go
outside to an area free from tall
obstructions to use your nüvi.
When your nüvi 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
.
