Yes, Bluetooth is required for wireless Android Auto.
While early versions of Android Auto required a physical USB connection between your Android device and the car's head unit, wireless Android Auto was introduced to eliminate the need for cables. However, even in the wireless mode, Bluetooth is still utilized for certain functions.
When using wireless Android Auto, your Android device establishes a Bluetooth connection with your car's head unit for functions like call audio, media streaming, and some control inputs. The wireless connection allows you to use Android Auto without physically plugging in your phone, providing more convenience and flexibility.
