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 Navigation screen
Symptom Cause Action (See)
Power doesn’t turn on.
The unit 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 the correct fuse with
the same rate.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly. Press RESET button. (

Manual” and refer to page 103 in this
manual.)
There’s no sound.
Volume level is low. The volume level is low. Adjust the
volume level. The attenuator is on. Turn the attenu-
ator off.
When the ignition switch is turned
ON (or turned to ACC), the motor
sounds. This unit confirms whether a disc is
loaded or not. This is a normal operation.
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 accu-
racy. (GPS satellites are operated by
the US Department of Defense, and
the US government reserves the right
to distort positioning data for military
reasons. This may lead to greater
positioning errors.)
•If a vehicle phone or cellular 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 50) and the position of the GPS
aerial if necessary, or continue driv-
ing until reception improves. Keep
the aerial clear.
Signals from the vehicle’s speed
pulse are not being picked up prop-
erly. Check that the cables are properly
connected. If necessary, consult the
dealer that installed the system.
The navigation unit may not be
mounted securely in your vehicle. Check that the navigation unit is
securely mounted and, if necessary,
consult the dealer that installed the
system.
