Sorry for the late answer. You cannot solve that without an additional module, at least for older model years, not sure for your 2017 yet, but it looks like it has the same problem as the old ones. Customtronix from Sweden will offer an "all-in-one" module for retrofit, soon. It will have the "Heated-Seats-Fix", the "Navigation-Message-Fix" for the cluster display and the "Custom-Units-Fix" (which is your issue). I will report as soon as it is available, or feel free to ask

Edit: Saw your solution with AlfaOBD. Congrats, hope, all works for you now. Older model years unfortunately have a lot more problems like completely missing or empty menus. CTX fixes that, too.
