Yes, I did do a search before I posted. I have been searching all morning all over the interwebz. My factory Mach460 finally bit the dust. CD play dead and volume control knob does what it wants when it wants. I have a lead on a working Mach1000 head unit. From what I have gathered, they are the same head unit, just labeled differently. The difference in the rest of the sound system is subs/amps. As long as the code on the radio matches up then, I should be good to go. Can anyone confirm this?
