Instruments and Controls 5-5 Compass The vehicle may have a compass display on the Driver Information Center (DIC). The compass receives its heading and other information from the Global Positioning System (GPS) antenna, StabiliTrak, and vehicle speed information. Avoid covering the GPS antenna for long periods of time with objects that may interfere with the antenna's ability to receive a satellite signal. See Backglass Antenna on page 7‑27 and Satellite Radio Antenna on page 7‑27 for the location of the vehicle's antennas. The compass system is designed to operate for a certain number of miles or degrees of turn before needing a signal from the GPS satellites. When the compass display shows CAL, drive the vehicle for a short distance in an open area where it can receive a GPS signal. The compass system will automatically determine when the GPS signal is restored and provide a heading again. See Compass Messages on page 5‑36 for more information on the messages that may be displayed for the compass. Setting the Time (Without Date Display) 1.
