I've got my stock head-unit in my 318is outfitted with an aux jack, but I'd love to connect that to an Airport Express in the glovebox so that I have a hidden wireless way to play music through the stock stereo. I have very little electrical know-how, but I'm guessing that whatever I tap into would be 12V, which would then need to be stepped down to the 3.3V that the Airport Express needs with a regulator or converter? Does that all sound right?
So if this plan sounds kosher, what can I tap into near the glovebox? And can anyone recommend a regulator?
