In the early B8 cars if you didn’t get NAV you got the old school red DIS and not the color version… I didn’t want nav but did want the color DIS but it wasn’t a show stopper… Honestly, I was more pissed that I couldn’t delete the fucking sunroof… So no Nav for me… The RS has Nav and I’ve used it… zero times… lol No I don’t know how to sail…
