Yeah, so I am new to owning a AVIC unit and new to this website. I was told you could update the software of a n1 to an n3. Could someone please escort to how I may do this?

Buy the disks, thats it. But it won't give you the improved ipod or XM display.

You will also find by using the search button how to make it play movies and do nav functions while in motion after you insert the new disk. It ain't easy
