I have just had a reversing camera fitted. I bought a used T-Cross which had all the spec I wanted, except the camera. The dealer offered a camera fit for about £460, it fitted into the number plate light housing. Research showed VW can be fitted with hi or low line reversing cameras. The hi line has the moving guides. I suspect the 460 camera was low line. Instead I opted for a company with specialises in VW and Audi retro fit accessories. This company put a reversing camera into a previous Golf I owned. The parts are all VW acquired direct from VW in Germany. The true factory fit camera for a T-Cross is part of the boot opening mechanism and is a hi line camera with moving guides, it also interacts with parking sensors if they were factory fitted. The cost was £800. You may get cheaper but in order to maintain warranty, VW parts should be fitted. I travelled 140 miles round trip to use this company as it's reputation is faultless. Depends where you are in the country. I used Advanced in car Technologies and they are based in Poole, Dorset. Advanced-incar.co.uk look on you tube at their videos. Hope this helps.
