I got mine upgraded. I have a 2012 F30 CPO I bought July'15. Lucky sod, the BMW Assist on it expires in Aug'18 so I opted to do the retrofit.

Knowing it costs $1100 just to do it, I chose that rather than $200 gift card.

All I can report is that comms seem obviously faster. Sending destination messages to myself for the NBT Nav. is much quicker now than before. But that's the only difference I can tell.

They had the car for 4 days thanks to an ice storm where I live, so I'm guessing it'd take overnight to normally do it. They said I was one of their first so they had to learn a few things and get additional cables and what not that they didn't have on hand.
