Space Star Bj 2023: Installation Rearview camera, experiences?

Hello everybody, we have a new Spar Star Select for a few days now and are very satisfied so far. The gearbox is a bit rough, but it will definitely be a little bit rough 🙂 Now to my question. I would like to install a rear-view camera at the Space Star on the license plate. I have already done this for other cars a few times before. Therefore, I hope there is sufficient craftsmanship. Unfortunately, I do not have any information on the experience on the Internet. ngen found for own installation of the rear camera. Unfortunately, there is also no repair manual to buy, in which e.g. the dismantling of the bumper, interior cladding etc, are described. Therefore, I turn to you. Has one of you installed a rear camera and if yes, how? I would like to install one with radio from Auto Vox. Accordingly, I would only have to remove the bumper (covering), use the cable guidance of the license plate lighting inwards and in the trunk In the front, I would try to display the video signal to the Pioneer multimedia radio via an adapter. That would save me an extra monitor. I would be very happy about help/experience sharing. Thank you and greeting, Daniel
