Compass/Temperature (C/T) Button
Actuating the Compass/Temperature Button (C/T) will cause the CMTC to display the compass and temperature information. This function will operate from another traveler display. The CMTC simultaneously displays the compass reading and the outside temperature. Vehicles equipped with the 3.7L or 4.7L engine receive outside temperature information via the PCI bus from the NGC. JTEC equipped vehicles receive outside temperature information via the PCI bus from the HVAC module.
The CMTC module internally senses and calculates the compass direction.
