Now that I am hearing multiple other individuals with this issue, I believe BMW will need to address it. I also thought bugs, sand or some other particles were hitting my windshield when I first encountered. When I went to turn the sound down to hear it better is when I heard the crackle static. It was volume related. Fortunately for me it is infrequent. It remits if I stop the car, shut it off for a few minutes then restart. I drove with it for awhile to see if would eventually go away and rapidly realized I would go nuts. I will post any new information I receive.
