(well that was fast) Interesting update. My observations: First attempt asked if I wanted to update the firmware. I selected 'yes', but it only flickered and went back to its usual powered-on mode. Shut it off & retried, and that time saw the "Processing..." screen for a minute or so. The screen went blank, and another 30 seconds later I hear maybe two seconds of static coming from the speaker before it shuts off.
I took the card out & removed the bin file, put it back in & powered up, saw the Ford logo. Checked & saw fw version 20140308 (it was at 0116 or something), so it seems to have taken. Some settings reset (1 min video loop when I had set 3min, video+audio when I use just video), but others seemed unchanged (English language, full HD). All seems well.
Will let you know when it fills up if there are any issues (takes me a few days).
