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 comprehensive, 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.
You cannot position your car on the map or the positioning error is large.
Possible causes:
(1) 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 aerial is in an unsuitable location.
• Obstacles are blocking signals from the satellites.
• The position of satellites relative to your car is bad.
• Signals from the GPS satellites have been modified to reduce accuracy. (GPS satellites are oper-
ated by the US Department of Defense, and the US government reserves the right to distort posi-
tioning data for military reasons. This may lead to greater positioning errors.)
(2) Signals from the car's speed pulse are not being picked up properly.
(3) The main unit may not be mounted securely in your car.
(4) Your car is operating in Simple hybrid mode (see "Positioning by dead reckoning" on page 173).
(5) Setting of Installation direction lever is wrong.
(6) Main unit is installed with extreme angle exceeding the limitation of the installation angle.
(7) Indication of the position of your car is misaligned after a U-turn or reversing.
Solutions:
(1) Check the GPS signal reception using "GPS Status" (see "Checking positioning information by sat-
ellite" on page 94) and the position of the GPS aerial if necessary, or continue driving until reception
improves.
(2) Check that the cables are properly connected. If necessary, consult the dealer that installed the sys-
tem.
(3) Check that the main unit is securely mounted and, if necessary, consult the dealer that installed the
system.
(4) Connect the speed signal input (pink lead wire) of the power wire correctly, and reset the 3D Hybrid
Sensor.
(5) Check the attachment position of the main unit of your Navigation System and the setting of the
Installation direction lever (see the "Installation Manual").
(6) Confirm the installation angle. (This unit must be installed within +30 degrees to -15 degrees of the
horizontal, or within five degrees of your car's direction of travel.)
(7) Check whether or not the reverse gear signal input lead (purple) is connected properly. (The Naviga-
tion System works properly without the lead connected, but positioning accuracy will be adversely
affected.)
The map continually reorients itself.
Possible causes:
The display is set to "Heading Up".
Solutions:
Check the "Map Orientation" settings (see "Map Orientation" on page 102) and change the setting to
"North Up".
Tracking marks are not displayed.
Possible causes:
The "Tracking Display" is turned off.
Solutions:
Check the "Tracking Display" settings (see "Tracking Display" on page 102) and make sure "On
(Always)" or "On (This journey)" is selected.
