I'm on S18D. Hopefully I will get an update soon. I might be taking it in for service next week. I'm brow beating my service rep to give me the updates. They said it was already up to date when I had it in for service a couple of weeks ago. Ridiculous.I am taking it in early next week. I have a list. I am on S18B on the infotainment system and probably neither of the other two updates have been done. We will see. Absolutely love the car though.
Strange things seem to happen with the InControl/Telematics, etc. when I drive the car and then turn it off. Drive again and turn it off and something else strange might be happening or not happening. Nothing big, just little annoyances like the app not connecting. I lost my app connection pretty much exactly when I stopped charging. Strange.
