I appreciate your experience with the F9. I don't have the need for the Carplay and Android Auto as I see many others have had, but I do have a problem with the interaction between the Tesla center screen and the F9 screen. Specifically, the steering wheel right hand thumbwheel appears to control both the left side of the F9 screen as well as the maximum speed of the cruise control on the Tesla screen, unfortunately at the same time. To explain further, when you are cruising along with the cruise control engaged and adjust the maximum speed with the right thumbwheel, the F9 also cycles the left third of the screen through the different options, such as tire pressure, theme, settings, etc. I requested some help from the Hansshow technical department, and their response was "This is normal. The right wheel controls the F9 and the car screen at the same time. There is currently no upgrade." Obviously, that was not very helpful. They could not appreciate the problem. Perhaps there is an easy fix, but I am not aware of it. It seems as most of the secret, unpublished downloads deal mainly with Apple Carplay and Android Auto problems.
