I have a avic90-dvd nav unit and a p6400cd head unit they were bought as soon as pioneer came out with em 2002,2003 paid 1500.00 for em and it was awesome worked great. But I had stored them for a while and now want to use em in a car I just bought. problems I cant find the cd for nav unit I would love to find how to get a copy of it.

I can get the updates but I believe its for touchscreen only units. I dont need touch screen but If I must upgrade Id rather upgrade to a new head unit, but keep my avic 90 any Ideas what head unit I can use to keep using the 90?

i have a 88dvd navi and i have the orginal i beleave 40's disks i could burn then and try to post the for you, i've never been able to post somthing to the net befor, so if these will work i'd be glad to help

I have two disks 40s I believe east and west but when trying to update I entered the east cd and it updated then gave me a enter original disk. I remember the disk I got originally was a single disk with a green colored face. Maybe Im doing something wrong. but also I found a service mode anyone know the password and what you can do in it?

ok i have the 80 disks so maybe the 40s would work...anyone else know?

yo will have to downgrade the unit and will need the remote to do that if i remebr right.. but the pw i up right up right down left down left i beleave
