Okay, here is the current status of my investigations:
- With the tuner disconnected, absolutely no phantom keypresses have turned up. This should also mean that the IR receiver is not the culprit (unless the tuner somehow influences the IR receiver and only when in the car).

Today, I re-attached the tuner and disabled the stalk input using the hijack config entry. I verified that the stalk is really dead now. During a one hour drive, I had 3 phantom events again.

This means that somehow the tuner is causing this, but not via the stalk input channel. Any good ideas what might be going on here?
