Thank you very much, greetings from Portugal. It was difficult to find your video but here I found it and managed to connect it to my astra, as it doesn't have Bluetooth included from the factory and I was able to play music or calls on my car's speakers 😁
How come the phone connects with Bluetooth for calls but not music yet if on a call the sat nav for instance will play through speakers so there’s a way to do it wirelessly
