Hey all,
I have a '17 S550e and my wife's '17 C350e camera resolution is better than mine. Is it possible to upgrade my cameras but keep it all OEM

Is it the camera or the screen resolution? I would think that would be easy to verify by comparing other identical items on the screens.

That's a good question. I would think the S-Class would have a higher resolution than a C. The MB graphics look crappy in the C but better in the S. But, it's a good question.

I don't see too many other 550e folks here, I have a 16' that I picked up CPO in 19' Super happy with my purchase, the camera seems pretty good to me but the only other cameras I have are aftermarket ones in my Nissan Xterra (Pionner aftermarket) and my wife's 21' Leaf Plus

The S, C, E, A, B, GLx, etc all should have the exact same resolution since the cameras are the same in all of them. If you want to see poor camera resolution, find an early W221 to take for a drive. After driving one of those, you'll think you have 4k resolution in your S.
