My LCI M2 is doing the same thing....just took the set up from the '15 M4 and moved it to the M2 but I have deemed it unusable. I used an extension and moved it around the cabin and for sure it is not the i-drive. I feel it is coming from the rear view mirror pod area. If i could come up with a cool mount set up to put on the outer edges of the cabin somehow it would be fine but........
I didn't use it mac anyways
My set up was blend mount, dual wiretap running V1 and Mobis dash cam both auto on
