Sad to say that my second K2 has died again. The 1st was replaced as an excellent piece of customer service in the UK by the distributor here, despite being out of warranty. It had water ingress, despite supposedly being waterproof, and being positioned in a well protected part on the bike.
Well I discovered tonight that the 2nd unit has also died. Some months ago it seems, as I rarely check the contents of the SD card to see what's been recorded. In the end, I expect to rely on it in case of accident, not to check whether such an expensive piece of kit is still working.
The unit goes into a continuous boot / reboot. Tried reinstalling firmware. Different SD card. Powered off USB instead of 12v adapter. The unit never wakes up properly and the WiFi is never established.
Extremely poor for such an expensive product, and still relatively young. Bike has only done 10,000 miles since new, and not done lots of wet rides. For one to fail is unfortunate, the second is more than coincidence and suggests just a poor quality product.
If anyone has any suggestions on wether it's possible to resurrect, am interested to hear before it heads to the nearest landfill site.
