Question about Kenwood DMX7722 Dabs

I recently installed this radio. I'm very disappointed with the software, especially Android Auto. Pretty much nothing works reliably. - The lower taskbar is often no longer operable and does not respond - Youtube Music often displays the error message "Background playback not possible" - Phone sometimes does not work "New version of Google App is required", although everything is up to date - Menu is very poorly translated e.g. "Close" is translated as "Nahe Dran" I would not have expected something like this from Kenwood....
