Moin, always something new. My comand should actually play DVDs – it does. I have an image, but no sound. Everything else works (CD changer). Not that I wanted to use this function on my walking trips ….. And another question: What do I have to do to play from iPhone music via Bluetooth via the comand? 3. Question: What is this interface? Is there only in connection with the code U518? So far I do not have a suitable interface Kabe I can find. Best regards Thomas
