fysmd. Yes, thanks. Updating the firmway seems to be the way to go. Unfortunately, for the last few days, blackvue.com website has been inaccesible, and now suddenly it isn't (inaccesible that is). Within the original software downloaded onto my PC there are two .html files, neither of which have a "key", nor is it obvious where or how the key should be inserted, so I haven't tried. I have downloaded the update but not yet installed it so I shall have to see how that works.
