So I've had my f90bt ever since the release date, all of the updates are current. However, a few days ago upon boot up the back up camera got stuck in view mode while I was driving. When I put the car in reverse, they back up camera went away and the menu appeared. (completely opposite of what is supposed to happen). I've rebooted many times with no luck.

So a couple days later I get in my car and the f90bt begins to boot up but then completely powers down. It has been doing this for the last 24 hours. I turn on the car and the splash screen is only up for about 10 seconds before the unit completely powers down. Someone please help! Do I have a defective unit or does it sound like a loose wire?

bring it to pioneer for repair

Have you tried resetting it?

I've tried hitting the reset button in front with a ballpoint pen numerous times. Is there a hard reset button somewhere?

try to see if you can boot into testmode. if you can then be go one way.. if it powers down when you try testmode you are shit outta luck and need service

how do I boot in test mode? Do I need to load a file into a usb drive? Is it the same way as doing an update?

read the faq on testmode in the hacks / mods section.
