INTRODUCTION:

Some customers may experience various malfunctions occurring with the multi-display. Some examples are:
- "Audio-Off" is shown on audio screen while audio system is playing.
- Climate control is not responsive and may say "Check connection of the air conditioner."
- Map, Destination buttons are inoperative and may display "External system not connected."
- When pressing any button on the multi-display, the system takes 5 to 10 seconds to respond to the user's input.
- Outside air temperature is not displayed.

A revised multi-display has been developed to resolve these conditions.
