Has anyone found a way to get this working or hide it when the center stack is enabled on cars before the 2020MY ?
I have not seen this work on pre-18.5MY vehicles. I did get it to display but you can’t change it on Sync 3.4 retrofits as far as I can tell. The menu just echoes what is in the General menu under Vehicle Units. This is likely vehicle dependent. I have not seen an adjustment to disable the menu.
