 Download the APK of the latest stable release from the [Releases page](https://github.com/BimmerGestalt/AAIdrive/releases/latest). Choose the one that says "sentry" to automatically upload crash reports, or choose "nonalytics" otherwise. It is also available on the [Google Play Store](https://play.google.com/store/apps/details?id=me.hufman.androidautoidrive). After starting, the app should detect the MyBMW app and start waiting for the car connection.
