So Ive been using my evo as a flash drive for music. I have an AVH4000DVD (Pioneer AVH-P4000DVD DVD receiver at Crutchfield.com) and before I had the evo I used a regular USB flash drive. Today I tried loading an MP4 onto the evo only to realize that it doesnt come up at all. Anyone else have any luck with this deck or similar decks? It doesnt have bluetooth. It doesnt list what files are compatible via USB only CD.
