FYI, there are three base gauge layouts, you can toggle them with the right arrow button on the left side of the wheel. Once you find what you like, ie dual tach and speedo or single tach in center with digital speed inside the circle (my favorite), hit the OK button in the center of the arrows buttons. This will give an opportunity to change and add display info. Use the up and down buttons to toggle different options available. Then use the left and right to move the options box and do the same. I think the return arrow saves the settings. Intuitive once you get past the first few button presses. Enjoy.
