There are two different hardware versions available dependent on the angle of installation in the vehicle (horizontal or vertical). The Mk-3 is compatible with both board monitor or MIR display units. (See workshop hints for configuration instructions). 

Identification of the Mk-3 computer over the previous versions is easy due to a change in the face plate design and the elimination of the "CD-IN" LED.
