Services, and Roadside Service are

. Press
Qto speak with an Advisor. OnStar or connected services cannot
work unless the vehicle is in a place
where OnStar has an agreement with
a wireless service provider for service
in that area. The wireless service
provider must also have coverage,
network capacity, reception, and
technology compatible with OnStar or
connected services. Service involving
location information about the vehicle
cannot work unless GPS signals are
available, unobstructed, and
compatible with the OnStar hardware.
OnStar or connected services may not
work if the OnStar equipment is not
properly installed or it has not been
properly maintained. If equipment or
software is added, connected,
or modified, OnStar or connected
services may not work. Other
problems beyond the control of
OnStar
—such as hills, tall buildings,
tunnels, weather, electrical system
design and architecture of the vehicle,
damage to the vehicle in a crash,
or wireless phone network congestion
or jamming —may prevent service.
See Radio Frequency Statement 0386.

Potential Issues
OnStar cannot perform Remote Door
Unlock or Stolen Vehicle Assistance

continuously for 10 days without an
ignition cycle. If the vehicle has not
been started for 10 days, OnStar can
contact Roadside Service or 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 and
underpasses; 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.
