My avic n1 was stolen but the brain wasnt, What heads will work besides the n1 ?

will the n2,n3,n4 and n5 ?

Anyone i see over 80 people looked at this post no answer?

I was just told by my Pioneer repair guy, that you can mix and match any of the n1,2, or 3 HU's & Brains....but the 4's and 5's won't mix with the 1, 2, or 3 brains. I don't know much about any of them as I just purchased a used one myself...but my Pioneer guy seems to know quite a bit and does repairs quickly and correctly with new parts.

any verdict on how that worked out? i want to replace my n2 headunit, the motors are shot and the screen seems to be having trouble. thought about getting a n3 off ebay or unless someone here has one.
