I purchased an Avic N1 off of ebay...when i bought it the box said N2 and the seller also claimed it to be an N2..well a month went by and i finally realized that i had the N1...i know im a dumbass...anyway...so i got a set of N2 disks and loaded them on ...well once I loaded the N2 disks i lost the ability to watch DVD's while in motion...So what im thinking is i need to install the N1 disks to regain that ability back...does anybody know how i go about uninstalling the N2 disks so i can load the N1 software?

There are a couple posts about forcing your unit to downgrade by doing something to its flash memory. There are many posts on this. I think the posts are several down from where yours is. If you cant find it try look at the N3 hack to rebypass it.

Both answers are available through searching athe N series post.
