When installing the Front X550 Dash Cam we always recommend mounting near the top of the windshield with the lens of the Dash Cam centred as much as possible.
You can connect the Dash Cam to power and use the Live View on the LCD Screen to help position the Dash Cam as well.
When installing the Rear View Camera* ensure that the Thinkware Logo is facing the interior of the vehicle to ensure the orientation is not upside down.
The Rear View Camera* should also be centred on your rear windshield between ant heating grid lines.
Unfortunately, we do not have a Video for running the Rear View Camera* wires as each vehicle is different.
