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 with the navigation screen
Symptom
The power doesn't turn on. The
navigation system doesn't oper-
ate.
The detachable device does not
turn on.
When you use the detachable
device removed from the main
unit, the battery runs out more
rapidly than before.
You cannot position your vehicle
on the map without a significant
positioning error.
You cannot position your vehicle
on the map without a significant
positioning error.
Cause
Leads and connectors are incor-
rectly connected.
The fuse (in the vehicle power char-
ger) is blown.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly.
The battery of the detachable device
is run down.
There's a possibility a new battery is
needed.
Signal quality from the GPS satel-
lites is poor causing reduced posi-
tioning accuracy. Such a loss of
signal quality may occur for the fol-
lowing reasons:
• This product is in an unsuitable lo-
cation.
• 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 cellular phone is used near
the GPS module, GPS reception
may be lost temporarily.
Something covers this product's
topside.
The navigation system may not be
mounted securely in your vehicle.
Action (Reference)
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 rating.
Press the RESET button. (Page 8)
Charge the battery. (Page 17)
Contact the nearest authorized Pioneer Ser-
vice Station.
Check the GPS signal reception, the position
of this product and the topside clearance if
necessary, or continue driving until reception
improves.
Do not cover this product with spray paint or
vehicle wax, because this may block the re-
ception of GPS signals.
Check that the navigation system is securely
mounted and, if necessary, consult the dealer
that installed the system.
