Sorry in advance for the dumb question!
There is no MOST hardware in the 2-Series audio systems however, you can code your OEM HU to output MOST as long as you run fiber optic cables from the OEM HU to the SMDI25. The dealer can sell you the OEM fiber optic cables and the terminations.

There is a thread in here of a member that did this MOST conversion, search for it.
