Compass Data
WARNING: This page is about a different car, the 2018 Cadillac XTS. However, it is still accessible from the selected car via links, so may be relevant.
With the Base Radio the Telematics Control module provides compass and GPS position information on the LS-GMLAN / Info-CAN bus when it is present.
In a Mid / High Radio System configuration without a Telematics Control Module and equipped with GPS, the radio shall provide the GPS and heading information on LS-GMLAN / Info-CAN as shown below.
An external Remote Compass Module (RCM) is required to transmit the heading and position information on LS-GMLAN / Info-CAN if either:
- The Base Radio is present in a system configuration with no Telematics control module.
- The radio variant without GPS is present in a system configuration with no Telematics control module.
