So the actual operating software (firmware) needs to be upgraded which must be done with an ICOM system. Not terribly difficult, just an expensive tool, and again my recommendation is that that you take the time to completely update every module in the car as its much easier to code properly later.
***The only downside is you will have to get an FSC code for BMW Apps and load it or load all new FSCs and wipe your unit like I did so you can get them all to match***
