I am told by numerous sources that the angle of the screens (both MID and NAV screen) are different between the e39 and e53. The e53 screen has more of an angle to it, apparently. I do admit, when I installed an e39 MID in my e53, the display was not as bright to my eyes from the drivers seat. So I found an e53 replacement and actually fixed the pixel on my bad e53 radio (and since sold it)

Sometimes she doesnt like how i treat her and sometimes i dont like how she behaves.
BUT at the end of the day, she loves it when I am inside her.
