Compass/Temperature (C/T) Button
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
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.
The CMTC module internally senses and calculates the compass direction.
