Here is what is my 2018 m2. Is this what you are looking for?
This is the remote
And the very sparse manual
Not sure the specifics of your inputs however in my unit if I want to watch the dvd in the entertainment center I select button one or push the button on the actual unit to move the light to dvd. If I want to watch over the air tv in the bedroom I select tv 2 and cycle through until I get to position 2. Or 3 if I want satellite. Then use location three for the outside tv.
Good luck.
