@Floridian, we're on the same page, just going at if from different directions. My goal is to have a digital dash and a smart steering wheel. Easiest way to accomplish that is to use CAN bus. VMSpec does a Windows based digital dash, but only works with an Allison transmission. I undestand that Torque Pro, an Android ap, works with the J1939 protocol now. I don't have the coach local so I can't test.
