Hi people, this is my first post so take it easy !!!
I have recently upgraded my stereo from a RCD310 to a RCD510 and everything works great except when I plug my iPhone 3GS into the mdi port the headunit does not recognise it when selecting media. If I plug my iPad in it will recognise that and play it as it should do. My iPhone worked when I had the RCD 310 so I don't see why it isn't working now. Any help or feedback would be greatly appreciated. My car is a 2009 mk6 gt tdi.
