Does anyone know how much it would cost to install a new head unit to my 2004 Lancer ES? I get an error code "E 01" when I insert a perfectly good cd in and I commute to school everyday, and occasionally drive 200+ miles on weekends to visit my family and girlfriend. What I mean to say is, I want something I could listen to, and a radio transmitter for my iPod is a definite no because my antennae is in the back of my car; I'll have to hold the radio transmitter on the ceiling of my car in the back in order for the signals to be intercepted. Any suggestions? I'm really considering just getting a new head unit with AUX and CD player to satisfy my need for music.
