windshield. This includes the
speedometer reading, rpm reading,
transmission position, outside air
temperature, the manual mode gear
range, and a brief display of the
current radio station, including XM
information or CD track. It will also
display turn-by-turn navigation
information if the vehicle has a navigation radio. The images are
projected by the HUD lens on the
