[1] Describe in detail the error you encountered:
If I set the navbar position to left, after the reboot and applying system update it's impossible to switch back to bottom position unless I do a config.txt flash with the xxx.xxx.navileft=true line removed (I forgot the exact string).
[2] Provide screenshots of system information, in the car settings - about - long press the upper left corner of the picture for 3 seconds, the contents of the pop-up window to take pictures:
^^
I'm using UIS7862 not UIS8581, it's a bug from the system information that should be fixed in the next version according tg @YAOXILONG
[3] Whether the bug can be reproduced, reproduced is what the steps are:
Go to HOME setting, in the Navbar menu, set the position to left. The unit will reboot and after reboot there's no way to set it back to bottom position.
