aye, it seems to work, however it opens a new window (I'm using Mozilla Firefox)...
from
kingnero.be it opens nice in the frameset, without opening new windows...
anyway, hope it helps,
On my car I haven't got the additional wiring, but those who have the Dash Illumination on their head unit, feel free to confirm it's pin 3 (or pin 6), there is a "speed of car" input as well on some models (to turn up the volume whilst driving), and I've read about an alarm trigger but I don't know that for sure...
