Yes …. And it’s fantastic. I solved one of my wife’s biggest complaints with them. She *hates* strong regen and drives with her X in “low regen”. Well, that’s not an option on my S …. Until I installed the S3XY Buttons module. Mounted a button on the column where the ignition would be, and she can press it to enable low-regen mode. Really changed her driving experience in a big big way. Worth its weight in gold right there.
On my S, we wrapped the rear seat latch hooks with tape. Eliminated the rattle altogether. Let me know if you’d like a photo.
