Long time lurker, i am glad i can contribute back to avic411 with the following info.
Doing a install today in a 08 Toyota Tundra with a avic-x910bt.
The bypass for video is the same thing as the bypass for the AVIC-F900bt. same pin swap, same grounding of the parking brake. i did a 10 mile loop with speeds up to 60 MPH and video stayed playing.
I did not connect the speed pulse.
I did ground the green wire.
i did swap the yellow black to the same empty pin location as the AVIC-F900bt.
If anyone else can confirm this method to work please please chime in. I would hate to pass
