The K2 stopped recording & wouldn't stay on, about halfway through the afternoon.
I haven't had this much trouble yet.
Changing my battery and formatting the SD card has helped, although I'm pretty sure that I still had some corrupt files after the changes, and definitely sometimes still get filenames that are out of order. I.e. instead of the (F)ront being odd and the (R)ear being even, they are reversed or one or the other is missing, which confuses the dashcam viewer a lot...
Also, previously I noted (and posted) that the serialization at the end of the filename was resetting every time I power cycled the bike/camera. However, with the new battery it no longer appears to be resetting with each trip. Not sure which is the correct behavior.
They think a ribbon cable inside the DVR is possibly coming loose, making the unit unable to stay powered up.
On the Innovv K2 forum, Rock mentioned that there is a new revision to the power adapter cube. I'm not sure how to tell which version I have, but when I contacted Innovv's tech support with my installation date, they indicated that I need the new adapter. However, the guys in the Nevada tech support center haven't been very responsive about getting one sent out.
I sent another email to Rock today... He wants to have me send the DVR back for testing, perhaps to check for that same ribbon cable issue you mentioned. However, my camera has not quit working altogether yet
like yours did. A sketchy power adapter could explain the corrupt files as well as the missing files based on the premise that it was turning itself off and on when it should have simply stayed on. But an intermittent connection of the ribbon cable could also explain it.
One thing I can't explain yet was why or how it factory reset itself. Ribbon cable too?
Based on the responsiveness of the guys in Nevada, I'm not too excited about sending in my DVR without some assurance that I will get it back in a timely manner.
