I don't think they would need to do much R&D since they would use the exact same software and hardware except add an OEM-style frame which is easy and program the buttons to do what they're labelled and steering controls. If a Chinese company like Dynavin can build a system for BMW and Mercedes then Kenwood and Pioneer should too. Again they wouldn't even need to change their software, just change the appearance of the frame and buttons.
Your car looks great by the way especially your steering wheel. I still can't stand the non-OEM looking head units though, they look extremely out of place.
