Mike, I have not researched the RV-C protocol yet, I currently don't have any devices that can use it.

I replaced the mechanical motor and transmission with the intent of going to digital gauges. I will continue the pursuit of replacing all analog gauges with digital ones.

My first concern is driveability, hands-free blue tooth, steering wheel control of cruise, headlights, wiper, radio, and paddle shifters. There are numerous manufactures of programable body control modules (BCMs) and Arduino CANbus readers to interpret all CANbus signals. Might take some time, but it's definitely doable.
