Pioneer SUPER TUNER AVIC-Z110BT - Manual (Page 178)

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 authorized Pioneer service facility.
Problems with the navigation screen
Symptom Cause Action (Reference)
The power doesn ’t turn on. The
navigation system doesn
’t oper-
ate.
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 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
“Acc
off
”. Then start the engine again, and turn the
power to the navigation system back on.
You cannot position your vehicle
on the map without a significant
positioning error. 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 antenna is in an unsuita-
ble 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 cellular
phone is used near the GPS anten-
na, GPS reception may be lost tem-
porarily. Check the GPS signal reception and the posi-
tion of the GPS antenna if necessary, or con-
tinue driving until reception improves. Keep
the antenna clear.
Something covers the GPS antenna. Do not cover the GPS antenna with spray
paint or vehicle wax, because this may block
the reception of GPS signals. Snow buildup
can also degrade the signals.
Signals from the vehicle ’s speed
pulse are not being picked up prop-
erly.
Check that the cables are properly connected.
If necessary, consult the dealer that installed
the system.
