Troubleshooting
If you have problems operating your navigation system, refer to this section. The most common prob-
lems are listed below, along with likely causes and solutions. While this list is not comprehensive, it
should answer your most common problems. If a solution to your problem cannot be found here, con-
tact your dealer or the nearest authorised Pioneer service facility.
Problems in the screen
Symptom Cause Action (See)
Power doesn’t turn on. The naviga-
tion system doesn’t operate.
Leads and connectors are incorrectly
connected.
Confirm once more that all connec-
tions are correct.
The fuse is blown. Rectify the reason for the fuse blow-
ing, then replace the fuse. Be very
sure to install a correct fuse with the
same rate.
Noise and other factors are causing
the internal memory to operate incor-
rectly.
Refer to “Returning the Navigation
System to the Default or Factory Set-
tings” and carry out appropriate
measures. (➞ Page 157)
The hard disk drive is not working
because the temperature is
extremely low or high.
Wait until the temperature inside the
vehicle falls or rises.
When the ignition switch is turned
ON (or turned to ACC), the motor
sounds.
This system confirms whether a disc
is loaded or not.
This is a normal operation.
The navigation does not boot up. The power cable is not wired cor-
rectly.
Turn the system off and the check
the wiring.
The hard disk drive is not running
because the temperature is too low.
Wait until the inside of the vehicle
warms up.
The hard disk drive is defective. Consult your authorised Pioneer
dealer.
You cannot position your vehicle on
the map or the positioning error is
large.
The quality of signals from the GPS
satellites is poor, causing reduced
positioning accuracy. Such a loss of
signal quality may happen for the fol-
lowing reasons:
• The GPS aerial is in an unsuitable
location.
• Obstacles are blocking signals
from the satellites.
• The position of satellites relative to
your vehicle is bad.
• Signals from the GPS satellites
have been modified to reduce
accuracy. (GPS satellites are oper-
ated by the US Department of
Defense, and the US government
reserves the right to distort posi-
tioning data for military reasons.
This may lead to greater position-
ing errors.)
• If a vehicle phone or mobile phone
is used near the GPS aerial, GPS
reception may be lost temporarily.
• Do not cover the GPS aerial with
spray paint or vehicle wax, because
this may block the reception of
GPS signals. Snow buildup can
also degrade the signals.
Check the GPS signal reception (➞
Page 81) and the position of the GPS
aerial if necessary, or continue driv-
ing until reception improves. Keep
the aerial clear.
