MMI navigation, audio artwork question
I have a new 8V with the MMI navigation package and Audi Sound System. I quickly discovered it can handle M4A encoded audio files straight out of iTunes on an SD card. Playback has been flawless, but I'm having a problem with artwork.
All my music is *meticulously* organized in a \artist\album layout, and I have placed a folder.jpg inside each album folder together with the individual music tracks. But, some album artwork shows on the MMI display, while other albums just show the generic music notes icon. At first, I thought it might be X-Y size issue, so I checked a few of the jpg's because the X and Y pixel counts are not the same for every image. Most are around 500 pixels on a side, some are larger and some are smaller. Even one which was 400x400 pixels does not show, while one that is 500x500 pixels does. Does anyone know what restriction, if any, there are for these files? Is it a filesize limit? How can I get the artwork to show for all my albums?
