- Launch the
Android Autoapp on your /e/OS device.
… OR connect your /e/OS device to the car. You can open theAndroid Autosettings from the head unit display in the car via the setting entry “More settings on the Smartphone” (roughly translated). TheAndroid Autosettings then get opened on your phone. - Scroll to the bottom and tap
Version10 times. - Navigate to Developer settings by tapping the
three-dot buttonat the top-right corner and tapingDeveloper settings. - Scroll down to
Unknown sourcesand turn itON.
