So I got this dash cam, the KD Links X1, and it plugs in to the cig lighter. It can also plug in to USB. Unfortunately, my mustang will try to read the dashcam as a storage device if I plug it in that way, in this mode the dashcam won't record video as it thinks it is being connected to a computer. So I was forced to use the cig lighter adapter. And that works as it should. Except for the part where the cig lighter continues to put out power while the car is off. The dashcam turns off, but does have it's own internal battery, when disconnected from power. It continues to be on and the cig lighter adapter is still lit blue as it is receiving power.
I have tried turning the car off, getting out, locking it, and then waiting a few minutes but you can see it is still on. Interestingly enough, if I remote start the car, then power gets cut from the cig lighter and the dashcam is off. So what I have been doing is unplugging the adapter when I leave the car. And that's annoying and should be more self automated.
I'm wondering if this sounds normal to others with the S550.
My only other idea is to cut a long USB cable in half, and only solder the power wires within it together. This way the dashcam will receive power but no info. That though just feels dumb lol.
