Engb
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 aerial 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
distort positioning data for military
reasons. This may lead to greater
positioning errors.)
If a vehicle phone or mobile phone is
used near the GPS aerial, GPS
reception may be lost temporarily.
Something is covering the GPS aerial.
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
satellites is poor, causing reduced
positioning accuracy. Check the GPS signal
reception and the position of the GPS
aerial if necessary.
The quality of signals from the GPS
satellites is poor, causing reduced
positioning accuracy. Check the GPS signal
reception and the position of the GPS
aerial if necessary, or continue driving
until reception improves. Keep the aerial
clean.
The quality of signals from the GPS
satellites is poor, causing reduced
positioning accuracy. Continue driving
until reception improves.
The quality of signals from the GPS
satellites is poor, causing reduced
positioning accuracy. Wait until reception
improves.
The quality of signals from the GPS
satellites is poor, causing reduced
positioning accuracy. When using a
mobile phone, keep the aerial of the
mobile phone away from the GPS aerial.
Do not cover the GPS aerial 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 44)
