Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Multi-Function Display
The MFD forms the basis of the high line audio system. It communicates with the rest of the audio system on the I/K-Bus. The Multi-Function Display controls all the radio, CD changer (optional) and cassette functions. The cassette unit is located behind the display panel and is accessed by pressing the "tape eject button". This causes the screen to move down and tilt slightly forward to reveal the cassette slot and eject the cassette. There is no option for a single slot CD player with the Multi-Function Display audio system. All other components of the audio system are the same as the low line system.
Diagnostics for the MFD are described in NAVIGATION SYSTEM .
