Hi all,
I recently picked up a used 2015 BMW M235i with the standard BMW audio speakers - not the HK upgrade. After driving the past week or so, I've noticed when I have my iPhone plugged in via USB or using Bluetooth, the audio on high notes tends to have some static that will occur and distort the audio. I originally figured it may be a tweeter issue for the speakers BUT when I decided to try AUX, there are no issues what so ever. I'm assuming it may be an iDrive/infotainment issue but not sure.
Please let me know what you think the issue is/possible solutions.
Thanks!
