To secure and connect the NAV ONE:
First, select a suitable location where the unit can be mounted vertically and clean the mounting area.
Then, separate the suction cup and mounting bracket assembly from the unit.
CAUTION
All air must
be removed.
1. FIRMLY press the suction cup against
the windshield by applying pressure to
the central PRESS button. Be sure the
button is pressed all the way in to make
sure ALL the air is out of the suction cup.
2. While maintaining FIRM pressure
on the button, rotate the lock lever
over the button.
Test suction cup adhesion by pulling on
the bracket. THE ASSEMBLY SHOULD NOT
WIGGLE. If it does, unlock the lever and
repeat steps 1 and 2.
3. Attach the unit to the mounting bracket
by means of the quick release feature.
4. Plug the power cord into the unit and
the vehicle's 12 volt power socket.
If the vehicle has a metallic coated or integrally heated windshield,
you may need to use the optional external antenna.
Use the quick release lever to temporarily
remove the unit from the mounting bracket
when the vehicle is parked to prevent theft
or heat damage. Be sure to turn off the power
before moving the unit to avoid damage to
the hard drive where the database is stored.
The suction cup portion of the bracket
can be left attached to the windshield
for quick reinstallation.
