The first thing is to insert the micro SD card. After that, connect the suction cup to the camera then stick it to the windshield at a point where it doesn’t obstruct the driver or the passenger, perhaps behind the rearview mirror.
Then, connect the power cable and wire it through the crevices to prevent it from getting in the way. Run it all the way to the cigarette lighter and plug it there.
Use adhesive tape to keep the wire attached to the truck’s wall.
