I think I read that 2014's you could not. Only Canada and Europe had the power folding mirrors and USA did not. I'm looking at a 2014 now and would love to be able to retro fit power folding mirrors. I did that to our 09' w211 with very little problems. Just needed to code the car which I can do from home. But would be nice to see if anyone has done or successfully done a retrofit.
