Media, Echo car, WLAN

Hello together, I have been driving an F11 BJ 2014 with the big Navi for several years. So far we connect our smartphones via Bluetooth to play music via streaming, but in the long run this is very cumbersome. I have now thought about switching to Amazon’s Echo car, also a WLAN hotspot would be practical in the car. Does anyone have any experience and tips on this? Thank you very much!
