The new version simply adds a joystick, which you can manipulate with a single finger, on top of the dial. The big advantage to this new system comes when browsing a map on the navigation system. Previously you had to keep switching between the x and y axis, twisting the dial to move along either. It was tedious. With the new joystick, we found it very easy to push the cursor all over the map.
Along with the improvement to the MMI, Audi updates its infotainment system by adding a hard drive for map and music storage. The hard drive makes for smoother map browsing, as the data access is quicker than with the previous DVD system.
