Troubleshooting
If you have problems operating your Navigation System, refer to this section. The most common prob-
lems are listed below, along with likely causes and solutions. While this list is not comprehensive, it
should answer your most common problems. If a solution to your problem cannot be found here, con-
tact your dealer or the nearest authorized Pioneer service facility.
Problems in the Navigation screen
Symptom
Cause
Action (See)
Power doesn’t turn on.
The unit doesn’t operate.
Leads and connectors are incorrectly
connected.
Confirm once more that all connec-
tions are correct.
The fuse is blown.
Rectify the reason for the fuse blow-
ing, then replace the fuse. Be very
sure to install the correct fuse with
the same rating.
You cannot position your vehicle on
the map or the positioning error is
large.
The quality of signals from the GPS
satellites is poor, causing reduced
positioning accuracy. Such a loss of
signal quality may happen 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 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 antenna, GPS
reception may be lost temporarily.
•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.
Check the GPS signal reception (

) and the position of the
GPS antenna if necessary, or con-
tinue driving until reception
improves. Keep the antenna clear.
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.
The navigation unit may not be
mounted securely in your vehicle.
Check that the navigation unit is
securely mounted and, if necessary,
consult the dealer that installed the
system.
Your vehicle is operating in Simple
hybrid mode.
Connect the speed signal input (pink
lead wire) of the power cable cor-
rectly, and clear the 3D Hybrid Sen-
sor memory (“
Learning Status
”).
The navigation unit is installed with
an extreme angle exceeding the limi-
tation of the installation angle.
Confirm the installation angle. (The
navigation system must be installed
30 degrees to –15 degrees of
the horizontal, or within five degrees
of your vehicle’s direction of travel.)
