The quality of signals fromthe GPS satellites
is poor, causing reducedpositioning accu-
racy. Check the GPS signalreception and the

If a vehicle phoneor cellular phone
is used near the GPSantenna, GPS
reception may be lost temporarily.
The quality of signals fromthe GPS satellites
is poor, causing reducedpositioning accu-
racy. When using a cellularphone, keep the
antenna of the cellular phone awayfrom the
GPS antenna.
Something covers the GPS antenna. Do notcover the GPS antenna with spray
paint or vehicle wax, because this may block
the reception of GPSsignals. Snowbuildup
can also degrade the signals.
