Hello, A while ago I tried to update my Pioneer Avic F910BT with new maps. I found 2014 Q2 maps. I used the testmode to copy the new map files. It worked fine for some days and then I got some error message. When I used testmode again to see the contents of My Flash Disk it seemed corrupted because the file and foldernames looked like strange characters. If only I had made a backup prior to doing this update...
I've had problems in the past and I was always able to reinstall a correctly working system. But for some reason now I just can't get it to work properly..
