Android Auto is the version of the Android operating system developed for cars, where we are not able to install applications with the same freedom as we can on a phone or tablet. Only those apps that have a Google certificate for being used in that environment will be displayed on the screen. However, there is a way of downloading supported apps that are not on Google Play. In order to be able to do this, you will need to download AAAD.Android Auto Apps Downloader: download any app in your car
This is an open-source app that allows for the downloading and installation of applications developed for Android Auto that are not in the official store and that offer interesting possibilities, such as navigation apps or multimedia players, to mention just a couple.
The app serves as an app launcher and takes care of downloading and installing software. However, you have to bear in mind that what you download might not work properly in your car. For now, the free version has certain limitations, such as the apps that it allows us to install or the number of them that can be downloaded monthly. But there is always the PRO version, which offers users greater flexibility.
