Embodiments of a method and readout system are shown and described whereby information regarding a vehicle's diagnostics and trip progress are displayed on the rear-view display or other monitor in the vehicle's cab. Information for display may include the vehicle's mileage, fuel consumption, speed, distances traveled, etc., and the relationship of the data to each other, such as average miles per gallon, average speed, time required for trip and to consume fuel, as well as such diagnostics warnings and information pertaining to oil temperature/pressure, water temperature, transmission temperature, fuel pressure, oil change need in engine or transmission and filter changes. This is accomplished by a microprocessor, which processes external variable data from a keyboard as well as via computerized components of the vehicle itself. The microprocessor generates the data which it has been instructed to generate by the system operator (microprocessor supervisor) and then transmits the data in alphanumeric form to an on-screen display (OSD) circuit, which is in position to be subsequently televised by the video monitor, which is already being used by the vehicle driver for rear-viewing purposes. Thus, the driver has immediate, undistracted access to vital vehicle/trip information as well as rearview images.
