OnStar 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 services. Service involving location
information about the vehicle cannot
work unless GPS signals are
available, unobstructed, and
compatible with the OnStar
hardware. OnStar 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 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.
