yeah I'm not thinking just the knob, I'm thinking the whole system!
I've watched people put so much effort into many devices like the Intravee, CarPC, Raspberry PiBus project, etc etc etc.....
All this is very exception work, but it all seems a little wasted when all most people want is an improvement to the OEM system that's more modern...aka iDrive!
Here are some examples of the kit I would like to install:
BMW 3ER F30 F31 F35 CIC Idrive Professional Navigation Multimedia Retrofit Parts | eBay
BMW X5 X6 E70 E71 Idrive Professional Navigation CCC DVD Navigationssystem | eBay
At the end of the day a system like this just needs 12v power and all the necessary signals from the car....
Maybe this is just to much to translate from iBus to the new systems, but also maybe not?
I wish I had the know-how, but I am not an electronics genius...
