Android car head units with Android 8.0 or newer.

How do I restore the stock launcher?
Open Settings → Apps → Default apps → Home app and select the stock launcher. Or uninstall CarDash, and the system returns to the stock launcher.
Are there ads? Does it work offline?
There are no ads. The launcher and dashboard work offline; internet is only needed for weather and update checks.
