Kia Venga – Retrofit rearview camera. Who’s done it?

Moin, I would like to retrofit a rear camera at my wife’s venga. I have already done this successfully with my Mondeo. Problem with the Venga: Where to go with the camera? Between rear flaps – handle and license plate light there is no room for a camera…. Now there are as I see 3 alternatives: 1.) Attach the camera next to the license plate light – then (from own experience with slightly inclined installation with my Mondeo) the image would be to estimate the reverse – do not go opti 2.) Camera from the inside behind the rear window. But here the viewing angle would probably not be optimal… 3.) license plate holder with built-in camera. Here I could even come behind the license plate with the cables into the tailgate to the license plate lamp. I am more a fan of wiring… Have you had experience with cameras that transmit the image by radio? Have read opposite opinions – from super to – The monitor receives any security camera in the vicinity – a about not own – or does the monitor approach during the journey by itself, because it receives any camera from ner Tanke or so… Are there instructions on how to get out the panels (back flap, sky, dashboard, etc. ) to lay the cables underneath? Where with the monitor? Do you have experiences? With my Mondeo I put a 7 ́ ́ monitor in front of the A-pillar of the passenger side. Alternatives would be: – Monitor in the rear mirror – Monitor in the storage box in front of the USB port (does someone have their monitor? Which one fits perfectly) – small monitor on the A-pillar driver side – small monitor over the radio… Thank you!
