I see, well you are right about that, not a lot -if any- is being done to carX, atleast no for the iBUS, the iDrive version and Audi version seem to get some attention as they are commercial and not free now.
BTW, would you happen to know if it is possible to get PDC (parking sensors) readings via IBUS? i am seriously thinking of doing my own front-end and want to have a nice visual effect of the parking distance remaining...etc.
Did you stumble on anything similiar through your search or through carmedia?

Thanks
