Frequently Asked Questions
How do I synchronize my information
clock to the navigation clock?
Drive your vehicle to an open area
where the GPS signal can be clearly
received and park. With the ignition on,
verify that the "GPS" indicator shows at
least 6 (GPS [6]) satellites. It may take
up to 5 minutes to establish the first
connection. Subsequent connections will
be faster (30 seconds to 1 minute), but if
you have not used the unit for several
days or are very far away from the last
location, it may take up to 5 minutes to
find a strong signal again. If you cannot
acquire the signal, drive to another
location. If the signal is still unobtainable,
check your antenna installation. Once a
GPS signal has been established, verify
that the information display clock time
(time displayed on the radio) matches
the navigation system clock.
I can't see the navigation display with
my sunglasses on. Why?
This device is equipped with polarization
technology and may not be viewed with
some polarized sunglasses. Please wear
non-polarized sunglasses or remove
your sunglasses when using the
navigation unit.
Why can't I can't find an address?
Since the road networks change
constantly with the addition of new
neighborhoods and other expansions, it
is possible the address you are seeking
is not present in the map data.
Why doesn't the system route me the
way I expect to go?
Your Routing Criteria will change your
route to use or avoid Toll Roads,
Highways, Ferries, etc. Modify your
preferences under Setup Routing Criteria
to see alternate routes.
Path from Main Menu: Setup > Setup
Routing Criteria.
Why can't I finish an address search?
On the data entry screens, the blank
button ( _ ) at the bottom center of the
screen functions as the "space" button.
Press the space button to complete the
search for entries with more than one
word. For example, to locate Lake Mary,
enter "Lake_" and then the "M" will
become available for selection.
