Pioneer AVIC-X3-II - Manual (Page 130)

Troubleshooting
If you have problems operating your navigation system, refer to this section. The most common
problems are listed below, along with likely causes and solutions. While this list is not comprehen-
sive, it should answer your most common problems. If a solution to your problem cannot be
found here, contact 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 incor-
rectly connected. Confirm once more that all connections are
correct.
The fuse is blown. Rectify the reason for the fuse blowing, then
replace the fuse. Be very sure to install a cor-
rect fuse with the same rate.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly. Press RESET button. (Refer to Page 24 in this
manual.)
The power turns on, but the unit
does not operate. The 30-pin cable has been discon-
nected and then reconnected. Press RESET button while the power is on.
When the ignition switch is
turned ON (or turned to ACC),
the motor sounds. The navigation system 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
following 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 mobile
phone is used near the GPS aerial,
GPS reception may be lost tempora-
rily. Check the GPS signal reception and the posi-
tion of the GPS aerial if necessary, or con-
tinue driving until reception improves. Keep
the aerial clear.
