Removed serviceable from a Cessna P-210N for an avionics upgrade. This moving map nearly eliminates the need for an IPAD in flight.

The MX-20's core feature is its map, shown on a large 6 inch display (640 x 480 pixels). Great care was taken with the design of the MX-20 to allow you to see the information you want, without inducing "information overload". For example, the map can be set to auto-zoom from waypoint to waypoint in your flight plan. You can scroll the map away from your intended flight path to view surrounding terrain and gather information about passing airports (including properly oriented runway diagrams). There are choices for map orientation, and you can put basic flight data in the corners. If you wish, you can see airways, water, roads, borders, and obstructions.

The MX-20 knows your altitude, because it is connected to your blind encoder (also used for Mode C). When you update your altimeter setting, you also tell the MX-20 the current pressure. The MX-20 then compares your altitude and known position against a terrain database, and color-codes the surrounding terrain based on the altitude difference:
