Front Display Interface Module (FDIM)

For vehicles without navigation, the Front Display Interface Module (FDIM) is a stand-alone module. It receives messages for all of its displays, which include:

• Audio information
• Climate control fan speed and temperature setting
• Outside air temperature
• Compass heading

For vehicles with navigation, the FDIM  is hardwired to the ACM  . When the touch screen is pressed, a signal is sent to the ACM  , which acts on the signal either by changing the audio setting or by sending a message via the MS-CAN  to the module controlling the function that was selected. The audio system, navigation, and climate control video feed to the FDIM  is provided by the ACM  . If equipped with a rear view camera, the video feed for the camera is provided by the rear view camera when the vehicle is in REVERSE.
