Having a sunshade for my M3P and knowing the benefits, I was looking forward to getting a sunshade for my 2021 MS. The single-piece MS sunshade is a tad tricky to install, not because it’s a single-piece design but installing the magnetic discs can be tricky. Without the magnetic discs the sunshade is droopy.
From the outside I divided the roof glass length in half and the width into thirds - I measured multiple times and put a tiny piece of blue tape on the axis. I stood a small flashlight shining through the outside glass at the taped axis and this helped me place the metal discs on the inside glass - placing the discs poorly will piss you off so you’ll want to get this right. The sunshade when unpacked is wrinkled so I ironed it and then installed it using the 8 side clips and the 2 magnets. Works well and does the job nicely.
