I'm replacing the Volvo satnav setup on my car with OpenAuto with a line-in for audio into the stereo and the video screen, which is only used for the satnav, being completely controlled by the Pi. The video screen is too far to reach a touchscreen. As such, I'm looking to add a new knob to use for control of OpenAuto with this setup, either through USB or Bluetooth. Does anyone know of a USB/BT knob that can already provide this functionality, most likely by keyboard emulation? If not, are there USB interfaces that can be attached to an iDrive (2009MY era) or similar knob? The one that I've used that I like the best is the one in newer Alfa Romeos, but I doubt I can get one affordably as they're quite new and not common in the US.
