Possible the HH mount is causing the barometric sensor problem. I used to own a K2, was active in the Hammerhead FaceBook group and cannot recall anybody ever complaining about this kind of problem, but would suggest to the OP that he join that group and post this problem.
Ohhhhhh my lord. Not a single time did I mention using the original Karoo mount anywhere in my post.
Sometimes I wonder if ppl actually read the posts.
Anyways, when I install another mount (which I have coming shortly) I will post back and see if that helps. Right now it works good on a simple garmin rubber and elastic top of the stem mount.
