Anyone has experience using the video input feature in the F500bt or f90? I put music files and video files in the SD. The F500bt only read the music files but does not recognize the video file. Any suggestion?

Video is fairly good through direct inputs. A/V input requires the 4 contact connector; tip and 2nd segment are audio, third segment is ground and base is video. I seem to get a buzz when I connect video only, no matter installed or on batt. (Could be my source: Nikon Coolpix.) I have the parking brake indicator grounded and get the "distraction warning" when the car begins to move. Seems only to require the warning once per startup, perhaps again if you toggle the A/V input. Rear-View works as well but the "Mirror Image" disclaimer is annoying.

I found out that WMV, MP4 format would work. However, the picture is only 20% of the screen size. Anyone know how to enlarge the picture to a full scree size?
