I am having the same problem with my f900bt system. I bought it a month ago and did the dvd bypass. On August 3rd my system went wacko and it keeps restarting every 2-5 mins. I called pioneer he said they need to do a system flash on there or i could order the 3.0 update and update that when i get it and it should fix the problem. He said the deck is not able to load the firmware. Please let me know if you figure out how to fix this problem. First i thought it could be a loose wiring or something... or not properly grounded.
