Honestly if I were you I'd be glad I didn't get the HK. I had the HK in one of my F30 335i's and the BavSound and Bimmertech amp on my second F30. The aftermarket setup sounded quite a bit better in my opinion. The other thing is that it's much easier to upgrade the base sound system as opposed to the HK.
