Alternative securement of the NAV ONE:
If it is not practical to mount the unit to the windshield with the supplied suction cup
and bracket, the user can develop an alternative mounting using the

-20 threaded
socket — compatible with most camera mounting equipment — in the bottom of
the unit. The supplied bracket may be removed or left attached when an alternative
mounting arrangement is employed. Additional mounting bracket options, that may
be more suited to your vehicle, are available at www.cobra.com.
After installation is complete and the vehicle is in an open area, turn on the unit.
The GPS signal strength indicator at the lower left corner of the LCD should show
four green bars to confirm the antenna is “seeing” the sky properly. If the bars are
fewer than four and are either yellow or red, the unit may need to be repositioned.
See page 65 in the Route guidance section for more information on the GPS
signal strength indicator.
When the GPS Navigation System is new (or has been idle for more than seven days
or has moved more than 500 miles while off), it can take up to five minutes for the
system to lock onto the GPS satellites. After such a start-up, the system should be
left turned on for at least 20 minutes to download GPS satellite data. Having updated
satellite data will allow much faster satellite acquisition and lock — typically less
than a minute — when the unit is turned on again.
