Don't these systems use Gracenote databases?There is something odd about how the display shows album art. I was listening to some Rory Gallagher that is loaded onto a USB drive and was recorded from several CD's.
The artwork on the display was some file photo of Gallagher and was not the album cover art from any of the CD sources. How and where did the infotainment system find that photo ? I always thought that some CD's contain a limited amount of metadata like the album cover and depending upon the playback source could display it. But the display was from who knows where in that case.
