located at the tip of the vehicle adapter.
1. Unscrew the black, round end piece,
and remove it.
2. Remove the fuse (glass and silver
cylinder), and replace with a 3A fast
blow fuse.
3. Ensure that the silver
tip is placed in the
black end piece.
Screw on the black

About GPS Satellite
Signals
Your nüvi 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 nüvi cannot 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 .
For more information about GPS, go to
www.garmin.com/aboutGPS.
