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. If a solution to your problem
cannot be found here, contact your dealer or the nearest authorised Pioneer service facility.
Problems with the navigation screen
Symptom Cause Action (Reference)
The power does not turn on. The
navigation system does not op-
erate. 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. Always install a correct fuse
with the same rating.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly. Park your vehicle in a safe place, and turn off
the engine. Turn the ignition key back to off
(ACC OFF). Then restart the engine, and turn
the power to the navigation system back on.
You cannot position your vehicle
on the map without a significant
positioning error. The GPS aerial is in an unsuitable
location. The quality of signals from the GPS satellites
is poor, impairing positioning accuracy.
Check the GPS signal reception and the posi-
tion of the GPS aerial if necessary.
Obstacles are blocking signals from
the satellites. The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Check the GPS signal reception and the
position of the GPS aerial if necessary, or con-
tinue driving until reception improves. Keep
the aerial clean.
The position of satellites relative to
your vehicle is inadequate. The quality of signals from the GPS satellites
is poor, impairing positioning accuracy. Con-
tinue driving until reception improves.
Signals from the GPS satellites have
been modified to reduce accuracy.
(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.) The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Wait until reception improves.
If a vehicle phone or mobile phone
is used near the GPS aerial, GPS re-
ception may be lost temporarily. The quality of signals from the GPS satellites
is poor, impairing positioning accuracy.
When using a mobile phone, keep its aerial
away from the GPS aerial.
You cannot position your vehicle
on the map without a significant
positioning error. Something is covering the GPS aer-
ial. Do not cover the GPS aerial with spray paint
or vehicle wax, because this may block the re-
ception of GPS signals. Snow buildup can
also degrade the signals.
Indication of the position of your ve-
hicle is misaligned after a U-turn or
reversing. Check whether or not the reverse gear signal
input lead (violet) is properly connected. (The
navigation system works properly without the
lead connected, but positioning accuracy will
be adversely affected.)
