AW: In order for a Huawei smartphone to work with Google services like Android Auto, the developer unlock option must be turned on. Unlocking is simple: tap the build number in the system settings seven times. After tapping 7 times, you will be prompted to enter the unlock password (if a password has been set). Enter this password. After that, the developer options are unlocked and can be found under the menu item System & Updates. After that, the Huawei smartphone should be able to be set up with Android Auto as described in the main device manual on pages 42/43.
