yep, I do have a stop/start, but this wasn’t a problem with my v1 until I replaced it with the v3. Working solid for a few years until white screen of death.As I've posted a few times, you need to be careful where you tap into.
These add on units (dashcam, SatNav etc) need a circuit that doesn't cut out when the starter motor cranks, and there are a lot that do. This puts the unit into a startup/shutdown confusion. This is more of a problem with stop/start vehicles. One benefit of the Viofo is the startup delay setting that can often help.
Also tried using the other hardwire kit for my back cam. Works fine. Changed all fuses too, still same issue
My guess is the old dash cam hwk is cactus. I can deduct this because the same line I tapped the V3 cam is the accessory line - same one ive got the USB cig lighter connected in to - which works just fine.
Either that, or the newer cams require a bit more juice on boot.
Next step is to put in a 3 wire kit, which I didn’t really want to do in case it one day fails and eats the battery, but oh well!
