You cannot position your vehicle
on the map without a significant
positioning error.
The GPS aerial 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 aerial 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 aerial if necessary, or con-
tinue driving until reception improves. Keep
the aerial clear.
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. Wait until reception improves.
