There is no GPS signal.
The GPS antenna is in an unsuitable
location.
The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Check the GPS signal reception and the
position of the GPS antenna if necessary.
Obstacles are blocking signals from
the satellites.
The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Check the GPS signal reception and the
position of the GPS antenna if necessary, or
continue driving until reception improves.
Keep the antenna clean.
The position of satellites relative to
your vehicle is inadequate.
The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Continue driving until reception im-
proves.
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.)
The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Continue driving until reception im-
proves.
If a vehicle phone or cellular phone
is used near the GPS antenna, GPS
reception may be lost temporarily.
The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. When using a cellular phone, keep the
antenna of the cellular phone away from the
GPS antenna.
Something covers 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.
