I was having an issue where the car's GPS would think I'm in a previous location many miles away, and would take several blocks before it realized. Seems to have been fixed so far. Not sure if this was your issueI got the OTA update a few days ago. It fixed the navigation issue I had. No problems at all downloading and installing - all was done automatically.
From a different threadUpdate: took my car in today. Technician said it was a glitch in the software. Came back after a few hours and remote start was working again. It must also be working from the key fob since I got notifications in CarNet when I was waiting at home. Invoice shows that they reinstalled Flex Guard. Hopefully this is the only time I have to do this. Winter in NYC is serious.
