Lumbar/headrest adjustment screen only displays temporarily (plus I could only get the passenger side headrest to go up-down. And no fine adjustments, only fully up or down. Driver's side wouldn't adjust) on main screen. Tesla needs to allow a much longer display.
Audio--no changes and XM is still as useless as before....
I thought the headrest adjustment on the display was just to select which function you are adjusting with the physical buttons - lumbar or headrest. Once you select headrest, you use the physical buttons to move it up or down. I didn't have any issue making minor adjustments.
