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.
NOTE:
If the TX+ or TX- wires are loose at the multi-display, the same symptoms will occur.
Please confirm that all connections at the multi-display are secure and that pin fit of the TX+ and TX- wiring is good before ordering a replacement
multi-display.
