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 with the navigation screen
Symptom
The power doesn't turn on. The
navigation system doesn't oper-
ate.
You cannot position your vehicle
on the map without a significant
positioning error.
Cause
Leads and connectors are incor-
rectly 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 occur 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 inadequate.
• 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.
Something covers the GPS aerial.
Signals from the vehicle's speed
pulse are not being picked up prop-
erly. (This information is intended
for AVIC-F900BT only.)
Action (See)
Confirm once more that all connections are
correct.
Rectify the reason for the fuse blowing, then
replace the fuse. Be very sure to install a cor-
rect fuse with the same rate.
Press RESET button. (Page 10)
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.
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.
Check that the cables are properly connected.
If necessary, consult the dealer that installed
the system.
