would this work on my M3 2006

I hope this does.....for my mp3 player and for my phone as well...?

No it won't work. That cable plugs into the CD changer port of a Kenwood stereo and convinces the stereo that the signal you're sending it (via the Mp3 player) is actually a CD changer.

If you want an aux input into your stereo then look HERE. that's a list I've put together of many different audio inputs for the Mz3 stereo depending on what kind of input you need.

Let me know if you need any further help, or have any other questions.

Look HERE for someone selling a PIE module for $35 (that's a great price). I think he has the RCA input, but you can get a different input adapter if you need a different connector.
