Are you sure it's coming from the info system? I have had the same noise from my M3 and found that it was the rear vision mirror. With the car running and in park place your ear 1 inch in from either end of your revision mirror and listen. Don't place your ear in the middle on the the rest vision mirror it's more prominent on the ends of the mirror. A stethoscope is a handy tool to use for this. I believe it has something to do with the drive in the anti glare mechanism in the mirror.

If you are in Sydney Australia have a chat with either James or Michael from Hornsby BMW these 2 legends the are all over this.
