I've only just decided to burn some mp3's for our 2007 Tucson which has the changer/mp3 player. Our regular cd's play fine but would love to put all of them on just a few discs. I've burnt 3 different brands of cd-r's, TDK, Maxell, Verbatim, on 3 different computers now. Finalized the cds. All kinds of mp3tracks from our cds made recently, and long ago. Every disc gets a 'no support' message on the player in the car after it tries to read the disc. But, weirdly, I can scroll through every track in every folder and see the name, length, etc., of each song. But the second after I release the scan/track button 'no support' rears it's ugly head again. Burning with Nero and once with xp media player(shudder). Just doing an iso file burn. Am I burning incorrectly maybe? Discs play files fine on the computers.
