The module "tricks" the car radio into thinking that the phone is connected, and then they communicate wirelessly via Bluetooth.

The module offers a fast connection between devices with which it has already been connected once. To do this, you have to turn on the ignition in the car, select "CarPlay/Android Auto" in the car, and then the connection will take place automatically.
Both the steering wheel buttons and “Hey Siri” and “Hey Google” will work.
You have to take into account that there is almost no delay after pressing the steering wheel button "next song" or changing the sound level. This situation happens unintentionally with a wireless connection.

The product itself is very small in size and can be easily hidden. This is especially good for cars that have a CarPlay/Android Auto USB port in the armrest of the center console, in which case it's hidden there and you never have to think about it again.

The product is only suitable for cars with wired CarPlay/Android Auto.
