Causes
Guidance voice level is set
to the minimum level.
The built-in microcomputer
may have functioned
incorrectly, etc.
The internal temperature
is too low. This is normal.
Internal protective circuitry
is working.
GPS antenna is affected by
the windshield if installed in
the car compartment.
The HDD is constantly
rotating at a high speed
when the car ignition switch
is on, causing imperceptible
mechanical noise (especially
when the temperature is
low).
There are no matching
points in your selected city
or area.
The entered point is out of
the navigable area.
You have tried to save the
current address into the
STORED ADDRESS (see
page 32) while you are out
of the navigable area.
Remedies
Adjust it to the optimum
level.
Reset the unit (see page 2).
Leave the power on, and
wait until the internal
temperature rises and the
indication goes off.
Install the GPS antenna
outside to avoid interference.
This is normal.
Find the location using
another method.
Enter a point within the
navigable area.
This is normal. You cannot
save the current address
if it is located out of the
navigable area.
