I just received my Scangauge2 also after owning the version 1 for about 7 months. I am having the exact same problem with mine, top line display only and no functioning buttons until a reset by unplugging the the connector. I have sent an inquiry to their service department. I really like the way it looks and it's functionality is the same as the version 1. I'd hate to have to return it for a refund.
