Thanks Luke for the Audio system coding.



My objective is to use an an Arduino to write short simple messages to the information display (just like the Radio does). I've seen this done by someone else in a VW? (was a random Youtube video years ago) and felt it was a neat compromise between aftermarket gauges and wanting more info in the car.


For example using the Arduino Analog input to read a combined oil temperature and pressure sensor and being able to display that on the cluster. Likewise the Arduino can control the oil pressure warning light on the dash based on those inputs!


We can naturally extend that idea to displaying anything we read from the Canbus, or that the Arduino can interface with in a timely manner.



I'll add to this thread as I get myself in gear and start playing around.
