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 screen
Symptom Cause Action (See)
Power doesn ’t turn on. The navi-
gation system 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 internal memory to operate in-
correctly. Refer to
“Page 168” and carry out appropriate
measures.
The hard disk drive is not working
because the temperature is extre-
mely 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
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.) 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. (Page 79)
