Hi, im new to the forums but have been following for quite some time. I have searched Google and the the forums a lot for an answer I can't seem to find. I have a 2013 Evo X GSR that I am looking to upgrade the head unit from the factory Rockford 6 disc to the factory nah unit. I have n-04 and n-05 models available to buy but not sure which to get. I know the n-05 is the newer model and should work fine but I did read on another post that the n-05 dropped some nice features that the n-04 did have. I was curious as to what these features and the actual differences between the two could be and which unit would be better overall. I haven't found anything about the differences searching! Thanks in advance!
