product doesn't operate.
GPS signal can not be obtained.
The screen is too bright.
46
En
Cause
Leads and connectors are incorrectly
connected.
The fuse is blown.
Noise and other factors are causing
the built-in microprocessor to oper-
ate incorrectly.
The GPS antenna is in an unsuitable
location.
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 accuracy.
(GPS satellites are operated by the US
Department of Defense, and the US
government reserves the right to dis-
tort positioning data for military rea-
sons. This may lead to greater posi-
tioning errors.)
If a vehicle phone or cellular phone is
used near the GPS antenna, GPS re-
ception may be lost temporarily.
Something is covering the GPS anten-
na.
Picture quality adjustment of the dis-
play is not correct.
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 in-
stall a correct fuse with the same rating.
Park your vehicle in a safe place, and turn
off the engine. Turn the ignition key back
to off (ACC OFF). Then start the engine
again, and turn the power to this product
back on.
The quality of signals from the GPS satel-
lites is poor, causing reduced positioning
accuracy. Check the GPS signal reception
and the position of the GPS antenna if
necessary.
The quality of signals from the GPS satel-
lites is poor, causing reduced positioning
accuracy. Check the GPS signal reception
and the position of the GPS antenna if
necessary, or continue driving until recep-
tion improves. Keep the antenna clean.
The quality of signals from the GPS satel-
lites is poor, causing reduced positioning
accuracy. Continue driving until reception
improves.
The quality of signals from the GPS satel-
lites is poor, causing reduced positioning
accuracy. Wait until reception improves.
The quality of signals from the GPS satel-
lites is poor, causing reduced positioning
accuracy. When using a cellular phone,
keep the antenna of the cellular phone
away from the GPS antenna.
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.
Adjust the picture quality. (Page 42)
