I have the same mount (which I love, and used for a long time with my HTC Droid DNA) and whenever I put the phone on the mount, Dot View mode would turn on, overriding car mode or anything else I had on the screen (like music, maps, etc). I just got off of customer support with HTC, and it looks like there's no way to turn this off. Any strong magnet will activate Dot View mode; it's a hardware feature with no software settings. Bummer - I love that mount. But I really like my new M8 as well, so I'll be looking around for other options, including the HTC-brand dash/window mount.
