I just hooked up my mp3 player to the N4 and enabled AV2 on the unit so I can listen to my songs. When I press the AV2 to enable it, the only option is Video. The music plays fine but on my screen it's just black with the time on the top left corner. I understand that my songs won't show up on the screen. I just want to know how to get my background along w/ the time to show? I can't find anywhere to change the settings. The only background settings I know is in the NAVI menu and all are set to the same custom background I added. Is there way to apply my custom background when in AV2 mode? I also plugged in my blackberry bold phone and it's the same results.

seeing as in av2 mode the HU is looking to play Audio and display Video I doubt there is any way to show your custom background when your mp3 player is hooked up. Just my .02 cents ...
