I am nursing a crazy idea to potentially completely re-engineer the multimedia/entertainment environment in E320, with a tablet main interface and a couple of backend Raspberry Pi's handling things like Bluetooth connectivity and media server duties. One element will include mounting an android tablet in the space where the current Comand NTG1 is bolted. Does anyone know of either: 1) Someone selling a mounting bezel that allows the physical mounting of a suitable sized tablet (ideally including the possibility to undock it and remove from the car, but not critical). 2) 3D CAD files of the S211 fitment Comand NTG1 unit with the hard mounting points - something that I can play around with and possibly use to generate a 3d printed adapter? I'll do it from scratch if necessary, just interested in making use of someone else's efforts if they exist. Many thanks in advance.
