I found this back in June. It's made by SoundGate and it's been available since the begining of this year (2009). It offers steering wheel and radio controls, charging, and (supposedly) even video output. I can't vouch for the quality or anything like that since I haven't used it myself, but I thought I'd pass on the information.
Here's its webpage from the manufacturer:

What I want to know is if this kit passes song Title and Artist text to the radio or not.
