Ok heres the deal. I have a avicn1 the i just got for $58.00 ( i work as a installer and this piece is way disco) and put into my civic. Now over the years i have aquired some N2 and N3 software brand new in the plastic wrap. I bought the CDIB100II for it as a GEXP910XM ( also way disco $8.00). Know my question is should i upgrade to the N3 software or the N2 software? I watch movies when i drive and i still want to keep that feature. Also the ipod adapter on the N1 sucks. So what should i do, i could probably get my hands on a N2 or N3 brain if needed. Just want all the info i can get before
