Correct- the ML without Nav does -not- include a DVD changer.
You'll note that ML without nav is no longer listed on lexus.com as a standalone option- this is a direct result of my experience receiving a car with ML and without Nav and not receiving the DVD changer that was listed as part of the ML package (regardless of getting Nav with it).
Both things you ask about (turn off ASL, turn off surround) are available with the non-nav ML.
