Hello dear r-drivers, I have been driving my 320 cdi in long 2008 and miss only one thing in the meantime painful: the media interface! meanwhile I have my ipad as a mediastation via aux as an alternative solution to comand aps (that without sd-slot); both for navigation as well as radio or ipod function. everything is also great, only recently I stumbled over these links:media interface plus in the usa media interface plus in Austria the media interface plus sounds somehow tempting. and according to the usa faq’s should also work in the r-class. does any of you know the part or is there someone who even has it??? now I ask myself if it makes sense to retrofit the media interface (code 518, if I remember correctly). that’s a prerequisite for the plus interface. what does the fun cost about that? I would also have a cd changer in the glove compartment, which I have never used before… there is any cable lösu ngen to replace the one with the media interface? would be great if someone could say something about it. or maybe you also know interesting alternative solutions!!! greeting r-surfer
