Hello Guys, Update: My Trailor Hitch ist now coded incl. SA Code 550, finally. A Trailor Hitch Expert Company coded it in first step, but there is no other way than go to MB Store to Final Code it in perfection. Cost 170 € for MB and 120 € for the Trailor Hitch Expert Company. But the 120 € could have been saved. If you are not correclty coding into HeadUnit your stuff. The Head Units Displays will alternate a Error until it eventually doesnt work at all!! Thats the point just a warning. Dont mess it up..
