My aftermarket JVC head unit in my old car would allow to me disable certain radio inputs. For example, in my Mitsubishi, I would love to be able to disable the AUX and AM and possibly even CD from even coming up when I cycle through the list of audio inputs. So when I hit Mode it would just go USB -> Bluetooth -> FM -> USB -> Bluetooth -> FM, etc. (or whatever the order might be) Anyone know if this is possible?
