using same Steering wheel controls for both computer and OEM Radio
Since the RcJoyCon sends hotkeys to the CarPC, you would have an application that would control a relay board using hotkeys, resistors connected to ground would be connected to the relay and would make a connection to the steering wheel control pins in the Car OEM Radio. If you route the Car OEM radio output audio into the CarPC aux port, and then route the CarPC sound through the car amplifier, the CarPC sound control would control the sound of the OEM radio. When you wanted to change the channel, mode etc. on the car radio, you would switch your front end to the application that controls the relays that send the resistance signal to the steering wheel controls on the OEM radio/Stereo.
