The front camera of my 20214 F12 started flickering but would eventually work. It did that for about 3 months and now it is not working at all. What are my options? Do you absolutely need to put an OEM camera that, I am sure, is outrageously expensive to produce an average quality picture? Are there some other cameras that would do the job? Did any if you have a re-wiring of the system done? I am in the dark here (no pun intended) and your advice/experience is welcome. I would really like to fix this because having to replace the front carbon splitter will be even more expensive. Thanks in advance!
