Troubles hooting
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 Cause Action (See)
The power doesn’t turn on. The
navigation system doesn’t oper-
ate.
Leads and connectors are incor-
rectly connected.
Confirm once more that all connections are
correct.
The fuse (in the vehicle power char-
ger) is blown.
Rectify the reason for the fuse blowing, then
replace the fuse. Be very sure to install a cor-
rect fuse with the same rate.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly.
Press RESET button. (Page 9)
You cannot position your vehicle
on the map without a significant
positioning error.
Signal quality from the GPS satel-
lites is poor causing reduced posi-
tioning accuracy. Such a lossof
signal quality may occur for the fol-
lowing reasons:
• This product is inan 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.
Check the GPS signal reception, the position
of this product and the topside clearance if
necessary, or continue driving until reception
improves.
Something covers this product’s
topside.
Do not cover this product with spray paint or
vehicle wax, because this may block the re-
ception of GPS signals.
You cannot position your vehicle
on the map without a significant
positioning error.
The navigation system may not be
mounted securely in your vehicle.
Check that the navigation system is securely
mounted and, if necessary, consult the dealer
that installed the system.
Indication of the position of your ve-
hicle is misaligned after a U-turn or
reversing.
Check whether or not the reverse gear signal
input lead (violet) is connected properly. (The
navigation system works properly without the
lead connected, but positioning accuracy will
be adversely affected.)
