Group 10: Interactive Scenarios

46. sitioning System (GPS)
“I live in Arizona. The sun out here is brutal and on top of that I drive my 2007 Suburban
East to work at dawn and West home at sunset. To keep from going blind I had my
windows tinted. When I got my vehicle back I noticed that the navigation system wasn’t
working. Could they have broken something?”
The agent should search for the 2007 Chevrolet Suburban manual and go to Navigation
Audio System > Global Positioning System (GPS).
The answer is: They probably didn’t break anything.
“The Navigation System determines the position of your vehicle by using satellite signals,
various vehicle signals, and map data. At times, other interferences such as the satellite
condition, road configuration, the condition of the vehicle and/or other circumstances can
interfere with the Navigation’s ability to determine the accurate position of the vehicle. The
GPS shows the current position of your vehicle using signals sent by the GPS Satellites of
the United States Department of Defense. When your vehicle is not receiving signals from
the satellites, a symbol will appear on the map screen. Refer to Symbols on page 20. This
system may not be available or interference may occur if the following happens:
• Signal obstructions caused by tall buildings, large trucks, tunnels,
• Objects located on top of the instrument panel,
• Satellites will not send signals if they are being repaired or improved,
• After-market glass tinting has been applied to the vehicle’s windows.
Notice: Do not apply after-market glass tinting to the vehicle’s windows. Glass tinting will
interfere with the system’s ability to receive GPS signals and cause the system to
malfunction. You might have to replace the window to correct the problem. This would not
be covered by your warranty.”

47. Reordering the Waypoints
“I’m sitting in my 2005 Trailblazer in my driveway and I just entered a bunch of way points
from my errand list. I just realized that the order on my errand list makes me go down
every street in town twice. It’s not a very big town, but still. Do I have to re-enter the way
point or can I change the order?”
The agent should use the Guide to Step-by-Step Documents to find the Delphi TSC Gen I
Navigation Step by Step Information document, then go to Section III: Setting and Deleting
Destinations> Reordering the Waypoints in Your Route. Then explain the procedure.
