Thank you Brian,

I already ordered the Ibus interface from Rolf. I am not sure how to link it to my E53 X5. I read that the easiest way is to use the CD changer, but which cable should I use between the interface and the changer ?

I do have a V29 OS on CD. That is not the latest but I didn't manage to burn a CD properly last time I tried, so I will have to do with this one..
