You cannot position your vehicle
on themap without asignificant
positioning error.
The quality ofsignals from the GPS
satellites ispoor, causing reduced
positioning accuracy. Sucha loss of
signal quality mayoccur for the fol-
lowing reasons:
• TheGPS antenna isin an unsuita-
ble location.
• Obstaclesare blocking signals
from thesatellites.
• Theposition of satellites relativeto
your vehicle is inadequate.
• Signalsfrom the GPS satellites
have beenmodified toreduce accu-
racy. (GPSsatellites areoperated by
the USDepartment ofDefense, and
the USgovernment reserves the
right todistort positioning data for
military reasons. This maylead to
greater positioning errors.)
• Ifa vehicle phoneor cellular
phone isused near the GPSanten-
na, GPSreception maybe lost tem-
porarily.
Check the GPSsignal reception andthe posi-
tion of the GPSantenna if necessary,or con-
tinue drivinguntil receptionimproves. Keep
the antenna clear.
Something covers theGPS antenna. Do notcover the GPSantenna with spray
paint or vehicle wax,because this mayblock
the receptionof GPS signals. Snowbuildup
can alsodegrade the signals.
Signals from the vehicle’sspeed
pulse arenot being pickedup prop-
erly. (This informationis intended
for AVIC-F900BTand AVIC -F90BT.)
Check thatthe cables areproperly connected.
If necessary,consu lt the dealerthat installed
the system.
