My 2006 Audi A6 All Road has some rust spots on the silver sills that run underneath the front and rear doors. I don't have a clue about cars and need some advice on how I might clean this rust up and hide it.

I have a 2006 3L Audi A6 All Road. It has turn based GPS but no maps and the color of the infotainment system is all red. All the other pictures of the Audi A6 and videos on YouTube from 2006 and 2005 show a full color screen. Any idea what the name is of the version I have and do you think it's upgradable?
