Hi all, Well I tried updating the firmware for my Pioneer F940BT. I downloaded the file from the orginal pioneer website. I got into the update menu, and it said it was erasing in the Ucom after that it gave me an CSS Error. I dont have a backup of my Pioneer, how can I reinstall it? The radio now only gives me a black screen and no reboot at all. Unit didnt want to turn off, so I had to disconnect my car battery. Could anyone help me? Thanks,
