Mine is still rebooting. I watched the battery voltage during startup and its fine. The unit usually starts its reboot sequence after the car is all ready running.

My F90BT is doing the same thing. 1 in about 60 tries, it will work. I use the term "work" loosely, as the navigation appears to be stuck on a spot that I have not been in for 3 days. Otherwise it will reboot, show booting for 8 to 12 seconds, go blank for 2 seconds, then reboot again. Pioneer SERIOUSLY needs to start noting these problems. This is annoying as hell, and I can't seem to find a fix.

I miss my D3. Never should have bought this stupid piece of $h!7.

My Problem is solved. I had the battery checked and it was bad. Replaced battery and ererything is fine. Now I have to go through all the settings and change where needed. 411 is great.

What do you mean under "Battery checked" ? How did you do it?

I am talking about the car battery being tested at a place like Sears. During the start it was not putting out a constant 10+ volts which the avic needs to start. If the avic detects less then 10 volts it will shut down. I had Sears install a new batery and problem solved.
