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
Power doesn't turn on.
The unit doesn't operate.
When the ignition switch is turned
ON (or turned to ACC), the motor
sounds.
You cannot position your vehicle on
the map or the positioning error is
large.
Cause
Leads and connectors are incorrectly
connected.
The fuse is blown.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly.
The navigation system confirms
whether a disc is loaded or not.
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.
Something covers the GPS aerial.
Signals from the vehicle's speed
pulse are not being picked up prop-
erly.
The navigation system may not be
mounted securely in your vehicle.
Your vehicle is operating in Simple
hybrid mode.
Action (See)
Confirm once more that all connec-
tions are correct.
Rectify the reason for the fuse blow-
ing, then replace the fuse. Be very
sure to install a correct fuse with the
same rate.
Press the RESET button. ( Refer to
page 125 in this manual.)
This is a normal operation.
Check the GPS signal reception (
Page 59) and the position of the GPS
aerial if necessary, or continue driv-
ing until reception improves. Keep
the aerial clear.
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 that the cables are properly
connected. If necessary, consult the
dealer that installed the system.
Check that the navigation system is
securely mounted and, if necessary,
consult the dealer that installed the
system.
Connect the speed signal input (pink
lead wire) of the power cable cor-
rectly, and reset the 3D Hybrid Sen-
sor memory ("Learning Status").
