thanks for the info, things are on hold again as I think i have got it working again but not 100%. I reflashed it, formatted sd card and it got going, tested this afternoon and seems to record ok now but the time is showing 1-1-1970 but the GPS works with speed and location ok. each 60 second file it creates the first 5 seconds duplicated the previous files last 5 seconds, so I don't know whats going on but it records ok now and I will keep an eye on it daily to see how it goes over the next week, still maybe a bin job but we will see.
I WILL NEVER OWN A BLACKSPEW AGAIN.
