Is there a way to go back to CNDV-60. I got a set of disk that are not working right. This is what is going on when put the east disk in my avic n2 and it satd that it was not the appropriate disk,but when i put the west disk in it seems to work but i dont have all the functions on my nav,such as drivers view on my screen and you cant break the distance down to 1 mile from where you are at.i live on the east coast so the west disk does me no good.And now when i put back in my 2006 disk in my unit it will not work,
How can I reset to go back to CNDV-60
Thx Mike
