Do you just press “M” button and then the button you wish to set? I want to set to button “1” so I press “M” and then “1”. I didn’t see a light or anything to confirm.

Can you set it to the key fob to have different memory seat setting so when you unlock the car, the seats move accordingly?

i.e. “1” is set to one key fob and “2” is set to another key fob?

Update - I figured it out.
