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 authorized Pioneer service facility.

Problems in the screen

Symptom
Power doesn't turn on. The unit
doesn't operate.
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 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 antenna is in an unsuita-
ble 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 cellular phone
is used near the GPS antenna, GPS
reception may be lost temporarily.
• Do not cover the GPS antenna with
spray paint or vehicle wax, because
this may block the reception of
GPS signals. Snow buildup can
also degrade the signals.
Signals from the vehicle's speed
pulse are not being picked up prop-
erly.
The navigation unit 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 the correct fuse with
the same rate.
➞
Press RESET button. ( "Hardware
Manual" and refer to page 113 in this
manual.)
Check the GPS signal reception (
Page 61) and the position of the GPS
antenna if necessary, or continue
driving until reception improves.
Keep the antenna clear.
Check that the cables are properly
connected. If necessary, consult the
dealer that installed the system.
Check that the navigation unit 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").
