Potential Issues
Some OnStar services are disabled
after five days. OnStar cannot
perform Remote Door Unlock or
Stolen Vehicle Assistance after the
vehicle has been off continuously
for five days. After five days, OnStar
can contact Roadside Assistance
and a locksmith to help gain access
to the vehicle.
Global Positioning
System (GPS)
.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels,
underpasses, or parking
garages; or in an area with very
dense trees. If GPS signals are
not available, the OnStar system
should still operate to call
OnStar. However, OnStar could
have difficulty identifying the
exact location.
.In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.
.A temporary loss of GPS can
cause loss of the ability to send
a Turn-by-Turn Navigation route.
The Advisor may give a verbal
route or may ask for a call back
after the vehicle is driven into an
open area.
Cellular and GPS Antennas
Avoid placing items over or near the
antenna to prevent blocking cellular
and GPS signal reception. Cellular
reception is required for OnStar to
send remote signals to the vehicle.
