Hello, i came from germany and this site is my last idea!

i had a avic f900bt after installing the firmware 2.009 from the pioneer page the radio only boot to the main screen and after 3-4 minutes the radio boots again.

in the search function i dont found anything that can help me.

thank you.

Reboots are software issues! The Avic is looking for a file, it can't find it and it then reboots itself. This sometimes happens when a firmware has been upgraded and previous mods were still on the system, or this can happen with a corrupt firmware file. I would try to reinstall the firmware and if that does not work, there is an all-in-one firmware package 3.1 in the Hacks/Mods section
