I am in the same boat. I got the upgrade done on Tuesday but they are waiting on the trim pieces. The bad news is that they didn't come in today, Thursday morning, so I took the car back. They really wrenched the trim pieces and got grease on the headliner. This is the third headliner put in the car and the third set of trim pieces because the car originally had grease on the headliner. Whatever you do, don't change the headliner. Also, don't expect the fit of the trim to have the same fit as from the factory. Also, ask for SYNC version 3.8 update. It was user installable briefly but was then made dealer-install only. I learned the dealer does not automatically upgrade SYNC. It has the Siri update which is pretty useless, but it least there is something.
