My 2016 A7 just came off lease and I leased a new 2018 A7. I was always impressed with the clarity and detail of the backup camera image on my 2016 even at night. On the new 2018, it's awful. A grainy picture. Lacks detail and is dark. Has anyone noticed this issue? If so, how have you resolved it? Can the dealer re-calibrate or modify the image contrast. Thanks in advance for your help.
