InControl is probably H251- Complimentary software update. When mine was done, the software update crashed and the car was off the road for two days while the dealer fixed it. When I got home, voice guidance on navigation didn't work. Another two days at the dealer to fix corrupted software. When I got home, I had lots of spurious warning messages. Found out that the battery charge was low, caused by incorrect shutdown of the OBD port by the dealer. Another day off the road while I reset and charged the battery. Informed the dealer by email. They didn't even have the courtesy to acknowlege my email. Hope you have better luck than I did. Check voice guidance on navigation before you leave the dealer - I've seen other instances of this reported.
