Not specifically DS7 related, but just out of curiosity. Are you using a dashcam and if so, which one? I used to have a 70mai A800S equipped with a rear camera. It was quite a decent dashcam. I’m thinking about getting an A810 4K this time which is the new, improved version. But I’m happy to hear about other’s experiences with dashcams.
I used to have a nextbase 522gw with rear cam too. I’ve always liked nextbase since you can hardwire them direct to the fusebox with their kits, and also wire them to a permanent-live, since their hardwire kit had a voltage monitor and automatically cuts off power if your battery falls below a certain voltage.
