While V7 contains some notable upgrades it contains a flaw which is also notable. Namely the HVAC system has a software bug where the car does not produce warm air. That's a problem when you get in a car with temps of 37F. When I contacted my SC they acknowledged it was a known problem, and suggested I simply turn the heat way up to fool the system. That worked, but then yesterday didn't. So I called the SC and they recommended shutting the car completely off and leaving it alone for 10 minutes. Inconvenient when you are trying to get to work, but it did solve the problem. While on the phone with the SC I asked if there was any way I could bring my car in and go back to the software version that was in the car when I took delivery 2 months ago, as having reliable heat offset things like the beta version of Autopilot. The answer was no. Not having reliable heat is a problem. I feel sorry for our Scandinavian brethren in the middle of winter.
