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 pressing problems. If a solution to your problem cannot be found here, contact your
dealer or the nearest authorised Pioneer service facility.
You cannot position your vehicle 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 vehicle 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 vehicle’s speed pulse are not being picked up properly.
(3) The main unit may not be mounted securely in your vehicle.
(4) Your vehicle is operating in Simple hybrid mode (see “Positioning by dead reckoning” on page
97).
(5) Setting of attachment direction lever is wrong.
(6) Main unit is installed with extreme angle exceeding the limitation of the installation angle.
Solutions:
(1) Check the GPS signal reception using “GPS Status” (see “Checking positioning information by
satellite” on page 81) 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
attachment 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 vehicle’s direction of travel.)
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 88) 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 88) and make sure “ON (per-
manently)” or “ON (current journey)” is selected.
