This is a possibility, but unfortunately you'd lose RDS - the mk2's radio feeds in at MPX (ie L+R+RDS) level, not just left/right. You'd also use your external serial port to control it.

But yes, this is a possibility. We're not done yet with the mk1 radio software though, at some point we should be doing a full align on it which will improve the quality of the signal when the car is moving.
