I am considering a 2018 Mazda 6 for my next vehicle. I've been doing a lot of reading and the rear camera seems to be severely lacking in quality. Is it possible to replace this camera? Are there any changes to the 2019 model year (which should be about now) whereas maybe this has been updated? This may replace a 2006 Acura TSX which has no camera so I suppose I can't complain, but my other vehicle is a 2013 Lexus which does have a pretty good one so that's my benchmark.
