Does anyone have any technical details on how the tuner interfaces with the empeg? I'm interested in how the empeg communicates with the tuner (i.e. tells it how to select stations, receives RDS information etc.) and also how the audio is moved from the tuner box to the empeg (analog or digital?)

I have contact with a DAB tuner module designer, and would be interested in how easy it would be to hook a DAB module up to the empeg tuner interface, ideally performing any necessary conversion in hardware, so that no software modifications were required.
