Safety regulations
The reversing system is an aid and does not relieve the driver of his
duty of care in road traffic according to STVO. Read these
instructions carefully before first use.
Product overview
The rear view camera sends a video signal from the camera via
WiFi (5GHz) to the smartphone. In case another Bluetooth
handsfree device is installed in your vehicle, it may cause
disturbances. Therefore we recommend to deactivate that other
Bluetooth handsfree device while using the reversing system.

Commissioning
Check the functionality of the components before installation (a
installed product is excluded from the return). Preparing and
installing the license plate holder.
NOTE: You may need a voltmeter to measure the polarity of the
electrical system.

CAUTION! If you have no experience in installing electrical
devices on vehicles, you are not allowed to carry out the
following work yourself. Have the assembly and connection
carried out by qualified specialists.
1. Remove your rear license plate including any holder that may be
present. Instead of the built-in holder, mount the license plate
holder with camera here - if possible using the old mounting holes.
First hold it up to the vehicle and prepare for installation:
2. Expose the interior behind the license plate so that you can see
the license plate carrier plate from the inside. In the area of the
license plate and license plate light, look for an existing cable duct
in the rear of the vehicle or in the tailgate. If there is no usable cable
passage here, you will have to drill your own cable passage. Mark a
drilling point that is hidden under the camera module or license
plate.
Note: You may need to drill a 6mm hole for the connection cable.
3. After drilling, seal the sheet metal edge with a suitable rust
preventive agent.
4. Push the connection cable through the hole into the vehicle and
connect the power wire to the connection cable. Carefully seal the
cable entry with a suitable body sealing compound so that no water
can get into the vehicle. Screw the license plate holder into place,
taking care not to damage the cable seal. If necessary, re-seal from
the inside.
5. Try to lay the power wire like it is seen in the below images. Make
sure that the cable routing is clean so that opening and closing
cannot break the cable.

Note: The pictures are just advice. Depending on your car it can be
a different way.

the trunk lid.

the bumper.
6. Remove the cover of the reverse light.
7. The thin two-core cable is used for power supply and as a
switching signal when reverse gear is engaged. Connect the two
wires with the two contacts of your reversing light. To do this, you
need to know their polarity (measure or check the circuit diagram):
The red cable must be mounted on the positive pole of the
reversing light and the black cable on an earth contact.
8. Install the tail light cover again.
Important: This installation only shows the rear view when the
reverse gear is chosen. Then the rear view camera gets power and
the WiFi signal is transmitted. The connected Smartphone shows
the rear view via App.
Note: If your 12V connection of the rear view camera has a
permanent plus the signal will be transmitted permanently. This can
drain the car battery!
Because of this we do not recommend a permanent
connection. If you want a permanent connection make sure it
linked with the ignition of the car!

the height of the license plate holder from
the ground.

The displayed lines on the Smartphone give you an indication of the
distance. Definitely control the distance with a folding ruler.
