I've gotten the 6.2 update 3 times now. I would get the reminder that my car is ready for an update. I would update it and it would be the same 6.2. They are happening about 2-3 weeks of each other. Are they revisions of the 6.2?
Yes - tap on the 'T' at the top-center of your screen. It will show you the build number. Likely something like 2.4.188.
Would you mind adding the upgrade data to the tracker (see my signature)?
