Maybe it's me but I just installed the Dasaita 12.3" Car Stereo for Toyota RAV4 2019-2022 Upgrade to 8GB+256GB and I went to customize the main screen and the only thing I can do is swap the top selection with the bottom, and I tried to add a widget on the other pages that had open slots and it doesn't add it. This seems extremely limiting not being able to tweak buttons screens etc.. please tell me im wrong! This should is all software so maybe there are releases that allow this?
