I had been meaning to post K9spud’s VWCDPIC audio interface adapter ever since our first auxiliary input hack… and today I finally remembered to. It really is one of the best out there. Normally the the Volkswagen OEM head unit has the CD changer channels muted unless you’ve got a factory changer. The VWCDPIC interfaces with the already present CD changer plug and fools the head unit to connect any audio device you want. It also provides remote control of your audio device using the head units buttons. It’s very clever and can work with any audio device.
