thanks for reply kiwi, that's the answer that i was afraid...so the only way is to make a gateway/translator for each canbus_to_kbus command...i read about that subject last days and my conclusion was about the same: there is no direct translation between buses anywhere on any bmw module so...making such a hw/sw gateway is beyond my knowledge...and, afaik, the guy who already made this scrap the project...it seems like the only way to add additional gadgets to my car is carputer with a front end sw like rr, cf and some ibus plugins and so...tough luck
