Google set out some new features in a blog post on Android devices by the end of last month. It includes features like password control, messaging, a dark theme for Google Maps and more. The post also highlighted some new Android Auto features, such as custom wallpapers, voice-activated games, keyboard shortcuts, and a new split-screen mode for cars with wider screens. Although some of these features are already available for several Android Auto users, the company has started rolling out the new split-screen support on cars with wide-screen headset units.
According to a recent report by Reddit user u / My_Name_Is_Taken, the new split screen layout has now started appearing for some Android Auto users. As you can see in the attached screenshot, the new layout shows two apps at once, with the primary app occupying a larger portion of the screen on the left and the secondary app occupying a relatively smaller portion on the right. In this particular case, the Spotify app can be seen on the left while Google Maps is on the right.
A note from Reddit user u / heresyfnord confirms that the split-screen mode users can also change the position of the programs. Simply put, your current primary app will always appear on the left and the second app on the right. So all you have to do is switch to another app, and it will appear on the left and the previous app will automatically switch to the right.
Although split screen mode is only available on wide headunits, there is a solution to get it on smaller headunits. As you noted / kv1dr, you can use an app like HeadUnit Reloaded to change the resolution of your Android Auto head unit, and the new split screen layout should start working as intended. If you do not have a wide screen header, you can download HeadUnit Reloaded by following this link.
