Just out of interest, how do you connect the Ibus interface to the cars electrical system? I presume you have to splice by the looks of it or is there a nice lead you can use?

Also, I understand sort of what this does and you need a mini PC etc but whats the REAL advantage of all this, for all the work involved, what would you use it for the most. Mine already has nav so dont want that, already have 6 disk cd so not too bothered about loads of mp3 although it would be nice, already have TV so dont need that, so not sure what else I can do with a computer in the car.
