I’ve only had two problems with this dashcam so far:
Sometimes it just doesn’t record. It seems to happen when I start the engine after the dashcam has gone beep. If I start the engine as soon as the gauges have done their thing and gone back to zero, it seems to work fine. I’m guessing it can handle a startup power glitch while the capacitor is charging, but not once it’s booted up.
A couple of times, it’s said ‘Card Error’ and refused to record. When that happened, I just turned the ignition off, let it power down, and turned it back on. Then it recorded. This may be due to my accidentally pulling the USB cable from my laptop without thinking a few days ago, which could have corrupted the flash filesystem, as it exports the flash as a raw filesystem. In future, I think I’ll reformat the card every time I access it via USB, just in case.
Also have a temporary rear install, with a second camera. I’ll update on that later.
