2014 bmw m235i, just two days ago my stereo system started acting up(some weird clicking noise coming from cd player) speakers work as i can use the radio function of it however the bluetooth and usb mode not working (although my phone says it’s connected to the car but car not acknowledging it and usb is charging my phone but again not acknowledging it) what can i start looking at to get this figured out? worked for a little bit but went back to the same thing. also would like to point out that the navigation system is also not loading, like it stays in that loading screen but never advances to the map or anything.
