That Gyro thing is a pain in the A$$ to get around sometimes, but in most avic's, they have a hidden switch you can do by paper clips to remove the gyro sensor from stopping the video, however wont effect your GPS. I did this with my avic N3 I had awhile back... My D3 was a little different, but worked none the less... As I stated... AVIC411.com has step by step bypass pictures for EVERY Pioneer in-dash... I'd check it out there if your having problems.
