Hello! I have a 2013 R59 Non-S and I've noticed lately that whenever I'm driving with the top down and have music playing all the way with the volume up, and whenever at random times when driving the volume will automatically lower itself and not adjust. And its not pleasantly lower, its significantly lower which definitely sucks some of the fun out of the drive. I have the S-Volume set to high, does this matter? I play music through a Bluetooth dongle that connects through aux to my iPhone.

When the volume lowers, I've tried shutting off the head unit, unplugging the Bluetooth, etc. but I can't figure out WHY it does this. Any ideas? OBviously I would LOVE to purchase a new whole sound system but I'm saving up to purchase right now. Help?!

Sorry I'm a n00b mini owner as of February.
