Well my idea may have run into a huge issue. I need to be able to use USB OTG and charge the tablet at the same time. I dont think thats possible currently.
My idea for the steering wheel controls were to use a Arduino and the AOA 2.0 spec to emulate a USB HID device. But I recently found a device called the JoyCon that does exactly that and is really easy to set up. I have ordered one and am waiting for it to get to my house.
I havent found any car amp that will accept an optical input. I either need a DAC that does RCA or use the 3.5mm and run it through an equalizer
