This is a tricky one, so bear with me. I drive a VW Golf Mk7 with the VW Composition Media System. I have an iPod nano 7th gen connected to the Media System through VW's own MDI connector to Lightning lead. Everything works fine with the nano in terms of navigating through playlists, albums and so on. Only problem is that album artwork only displays at roughly half size in the artwork panel in the media touchscreen. However when I connect my iPhone 5 with the same lead, artwork displays at the correct size on the screen. Music is a mixture of albums purchased from iTunes and my own tracks ripped from CD. For the latter, I always used high quality album artwork. Help!
