hi there, i just bought a seat leon 2017 fr facelift version with the 8 inch headunit, i want to put a backup camera in it as the review visibility is quite bad in this car but seat says that wont place one, has anyone did the same thing? any beneficts of going with the oem camera like pre wired cables and better compatibility with the original headunit? or some retrofit kits ? i previous had a seat ibiza 1.2 tsi 6j fr an aliexpress camera did the job has it his headunit was also a chinese android unit
