Guys I just got a Avic N4 and i dont have the brain. I was wondering if any of the other N series brain will work the N4, I know from reading the forums that the N4 brain wont work with the other headunits, but I cant find anything about the N4 working with other brains? Thanks let me know

Maybe the N5 brain, doubt any of the older ones though

Man, I was hoping that any of the N1, N2 , or N3 brains would work, hard to find any N4's and N5's brains for sale.

anybody else got a idea

Anybody else know a for sure answer?
