Navigation System Description and Operation (with CW1): Radio
WARNING: This page is about a different car, the 2015 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
The Radio is connected to both the Human Machine Interface and Navigation Control Modules via several connections. The Radio receives both Stereo and Mono audio from multiple audio circuits at the Navigation Control module and also receives audio from the Human Machine Interface via MOST Serial Data. The Radio then outputs this audio via MOST bus.
