I was wondering if anybody else has tried this? Right now I have an N2 w/ a N3 brain and it works great, but when I hook up the N4 brain the screen stay black and none of the buttons work. But I do hear it processing, any help or foresight would be appreciated.

Not going to work, the N1/2/3 are one species, and the N4/5 are another. There is no Platypus here.

He is correct! I have a N2 and I tried an N4 brain and it did not work! I want the IPOD menu with my N2 but I guess its not going to happen.

So the iPOD search functions would not show up if I upgraded my N2 brain to an N3? I currently have the complete N2 setup with the iPOD adapter. What about charging of the iPOD with the N3 brain?

Anyone know???
