Install went quick & easy thanks to all the forum info - recommend you look at the new silver roll over covers and see where the ball connectors are - use a flat screwdriver at that location and separate the silver back cover at those points so the screwdriver has best leverage - move it out a little bit at each connector point and work your way around - should be no problem not damaging the black front covers.
Really not a lot of physical product for the $400-$500 but its engineered nicely (like I'd expect from BMW) and stows nicely behind the seats. Pics below - Cheers Ross
