soooo i thought i was slick but it backfired on me

so some of u might remember how i was kinda complaining how the avic n1 has crappy maps and there outdated for my area and what not, well... there is an updated gps system called the avic-d1 so what i did was took the "west" disc to see what happens and then i loaded it in and it updated it and then gave me this msg that is wasnt the right disc for the device so i put in my old disc and it said pls wait or something and now my GPS map wont work, it shows all blank even when im on main roads, it doesnt move or n e thing

anyway to reset it or fix it??

thanks!

 

That happen to me to except for I use the avic-n2 disk to upgrade. I try to watch a movie while driving and I couldn't, so I put back the Avic-n1 disk in and it didn't load, good thing I had a service plan from Best Buy because it was a 220 dollar repair.

 

sh|t so its not reversable??
