Problem/Question Solution/Answer
My nüvi never gets
satellite signals.
Take your nüvi outside, away from tall buildings and trees.
Remain stationary for several minutes.
How do I know my nüvi
is in USB Mass Storage
Mode?
When your nüvi is in USB Mass Storage Mode, a picture of a nüvi
connected to a computer is shown. Also, you should see two new
removable disk drives listed in My Computer.
My computer never
senses that the nüvi is
connected.
1. Unplug the USB cable from your computer.
2. Turn the nüvi off.
3. Plug the USB cable into your computer and your nüvi. The
nüvi automatically turns on and goes into USB Mass Storage
Mode.
I cannot see any new
removable drives in my
list of drives.
If you have several network drives mapped on your computer,
Windows may have trouble assigning drive letters to your nüvi
drives. See your operating system’s help le to learn how to
map/assign drive letters.
The suction cup will not
stay on my windshield.
Clean the suction cup and windshield with rubbing alcohol. Dry
with a clean, dry cloth. Mount the suction cup as described on
page 2.
The touch screen is not
responding to my taps
properly.
1. Turn the unit off.
2. Press and hold the
Power button for about one minute
until the Calibration screen appears.
3. Follow the on-screen instructions.
I cannot get trafc
information.
Note: You must have a
GTM trafc receiver to
receive trafc data.
Verify that you are in a coverage area. You must be in a coverage
area to get the trafc information for that area.
Verify that the FM TMC Trafc Receiver is connected to the
power connector on the cradle and also connected to a power
outlet in your vehicle.
