I've installed the front cam today. The Thinkware 12V connector fits into the cam (same connector as the other models). The cam itself is very stealthy.

Since both cables are very thick, especially the rear cam cable, i have a hard time to hide them in my car. Frameless side windows don't help... cables are hanging from the roof now.
The fov is enough to see both A pillars (car is more than 2m wide). I've put it 2-3cm away from my rearview mirror compartment. Since the lenses are close to the windshield, nothing from it can be seen in the video. Blaclvue cam would show the mirror and radar housing (less road).
256GB Samsung SD card works fine. No problems so far. In case you need bigger cards, go for it.
The cam needs 4 to 5 seconds to start recording, when you start the engine. (Blackvue dr900s needs nearly 30s!)
Thinkware apo works good, but i have to turn bluetooth off to connect to the cam (Samsung s9+). No problem, since once you set it up you can ignore it.
Have to install the rear cam and hide the cables before i can make some recordings...
Edit: the cam gets very hot! It's ~15°C outside and the cam could be used as a heater.
