What is a Security Location?
Your security location should be a
location you return to often, such as
your home. If the nüvi has satellite
signals and you are at the security
location, you do not need to enter
the PIN.
Calibrating the Screen
If the touchscreen is not responding
properly, calibrate the touchscreen.
1. Turn off the nüvi.
2. Turn the nüvi back on and touch
the upper-left corner for about
30 seconds until the calibration
screen appears (white screen
with “Press dot”).
Updating the Software
1. Connect the nüvi to your
computer using the mini-USB
cable. The AutoPlay menu
appears.
2. Double-click on
Install
myGarmin Agent to open the
myGarmin Agent download page.
3. Follow the on-screen instructions.
NOTE: If the AutoPlay menu does
not open, or you are on a Mac
computer, go to www.garmin
.com/agent.
After you have installed myGarmin
Agent, you will be prompted to
open myDashboard when you
connect your nüvi to your computer.
myDashboard checks your nüvi
for current software and provides
additional information about your
nüvi.
