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 authorized Pioneer service facility.
Problems in the navigation screen

En
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 30-pin cable has been discon-
nected and then reconnected.
The navigation system confirms
whether a disc is loaded or not.
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 antenna is in an unsuita-
ble 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.)
• If a vehicle phone or cellular
phone is used near the GPS anten-
na, GPS reception may be lost tem-
porarily.
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. (Refer to Page 28 in this
manual.)
Press RESET button while the power is on.
This is a normal operation.
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.
