Yep - awaiting delivery of one.
I doubt it will make a difference, but we'll see.
Just to update on the issue in my posts.
I must apologise for the length of time that has passed since my last reply however. Issues with my second car have necessitated me using the car with the subject dashcam every day, so I havent had a chance to recreate the issue.
Anyway, I've recently gotten my second car back, and the car with the subject camera was parked for about 6 days, with a new memory card I got a few weeks ago.
When I started the car on the sixth day, the camera immediately powered up on its own [emoji2]. Usually after being down for a couple days, I would have to fiddle with either the power button, the power cable, or the memory card to get the camera to turn on.
So it seems as though the problem was the card. Of course the date and time reset because of the length of time it was off, but my issue (not automatically powering on after being down for an extended period) appears resolved.
Thanks again for the guidance provided.
