Bumping an old thread, but it is the closest to the situation I am faced with currently.
I have a similar question, from my searching it appears that it's not possible to control the dash display with any aftermarket stereo. These searches are by no means conclusive, and this thread: Replacing Scenic II CD head unit
seems to contradict this information. I checked Autoleads, and the pc 911 series appears to just grab the head unit's manufacturer and display that. Not worth if you ask me. Another source has this : http://www.caraudioplus.co.uk/Instal...isplay_Adapter
which claims to put up id3 tag info, but would require a supported Sony head unit.
I am also not an audio professional or even amateur hobbyist. I just want to use the stereo from my old car (card reader, bluetooth handsfree + A2DP, mp3/wma CD and aux in) and go.
As another option, I could buy a new stereo that will take the stalk controls and do something useful with the in-dash display. Has anyone had any success with what I would like to do?
