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
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.
Action (Reference)
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 rating.
Park your vehicle in a safe place, and turn off
the engine. Turn the ignition key back to "Acc
off". Then start the engine again, and turn the
power to the navigation system back on.
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.
