a quick check that i did brought up no results. I do know the older HiFi system was made by Nuvo, and it seems like this one may be too, so maybe they might be able to shed some light on if there are any other devices planned to work with it in the works. Other than that i'm guessing if you used something like nuvo's radio tuners plugged in to a computer via a serial connection to a computer and using a program like CQC (if someone could get ahold of the communication protocol for the hifi2 and write a driver for it) then cqc could feed the metadata to the keypads.. but it seems like a lot of work.
