Yesterday I had my phone plugged into my aux input and randomly it made an awful high pitch static noise and stopped working, I purchased another kit for the aux input but that also failed to do anything.
Tried looking it up online but nothing of any help, when the car is on the aux channel it just makes a static noise and if it’s plugged in nothing plays through the speakers.

Anyone had this happen before?

for the BA?

Yes, BA

why do you plug in the ph?. i use a bluetooth adapter for mine.
