I had this done recently, however today, I was cleaning up the z after storage and was scrolling through the iDrive and found a ton of added features (which are non-functional by the way). They obviously updated the software with features from a newer model, which don't work, sadly because there are some pretty nifty looking new features! Took some pics, hopefully they load up ok had to resize them. I posted here, because prior to the recall, these features didn't exist, so presumably, were done after the recall work. Funny though, didn't mention anything about a software update on the work order.....
