I was tired connecting my cellphone with an old cassette adapter to my VW Golf with an Beta 5 in it. I needed something new, something cool. And here it is, a fully functional interface between the Beta 5 and any device you want to play the music with.

This project raised out of an ebay search: I just wanted to know if there is a solution to get an AUX input on the car radio. Yes there is, even complete mp3 players are available. But that’s not what I wanted – at first!

Then I started digging the web for more info about the protocol the radio talks to cd changers.
The idea was to build a tiny thingy that fakes a cd changer and simply enables the AUX input (as it is available in several online stores). But during the development my ambition became greater and I wanted to read the keys pressed on the radio to remote control my RPi.
