occur in a large city with tall

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
Cellular reception is required
for OnStar to send remote
signals to the vehicle. Do not
place items over or near the
