Hello, I have a huge issue, I have a Avic x930bt, it happened out of the clear blue I started my car up and it wouldn't boot up. All I would get is the Pioneer splash screen and it stays there, I tried to download the update for the firmware and put it in but it did not work. Now I am trying to just go back to the original 3.00 firmware but I don't know how to get it and reinstall it so it can work again. Does anyone have any ideas on how this works and can help? Very much appreciate it skip.
