I am having a similar issue to many here on the forums, but with slightly different symptoms. I did quite a bit of searching in these forums before deciding to post a new topic.
My self-installed AVIC-F700BT ran fine for over 3 months now. I do not have a backup camera, but I did do the wiring harness trick so I can use the GPS while driving.
Yesterday evening, as I was leaving my neighborhood, I noticed the screen was black. I pulled over and restarted my car. The splash screen came up, but after the standard 20 seconds, the unit went black. The screen, the buttons... everything. Of course, like everyone, I can still hear the fan.
I have tried waiting a few minutes and pressing the buttons, but I can't get any response out of the unit.
I have tried hitting the reset button. The unit resets, and the same Start Up Screen > Nothing issue occurs. I have tried holding the reset button down different lengths of time, with the same result.
I have tried to reset the unit into "safe mode", but hitting the reset button and the eject button simultaneously. The unit resets, the buttons pulsate quickly while the startup/splash screen shows and it stays in this state indefinitely. I have let it sit for several minutes and the splash screen stays on and the buttons pulse. I tried to learn more about safe mode, but my searches in this forum on that subject did not yield good results. Where can I find more info on safe mode and different types of resets?
I have taken the unit completely out and disconnected everything, rechecking my connections as I reinstalled it.
My hope is that if I could only get to some sort of screen other than the splash screen, I could adjust the backup camera setting and everything would be fine.
Any help or suggestions would be greatly appreciated as I leave on a 600+ mile road trip in the morning.
