i have an avic n1 with a secondary 7 inch monitor. anyone know of a way i can play MP3s with visuals like winamp to play on the secondary monitor? the avic does not have audio visuals so i take it i would need to hook up an external source to the head unit? is hooking up a pc to my head unit the only option? i know i can already play mp3s with my head unit, i just would like some visuals while they play.
