To stream music via bluetooth to the stereo, your car needs to support A2DP (advanced audio distribution profile) standard which is not as common as the HFP (hands-free profile) used for phone-calls.
Even though both A2DP and HFP is using the same bluetooth connection, the A2DP requires more computing power and different software to support that feature.
Car media systems developed 15 years ago (like for example Audi MMI 2G) where not ready for such technology as it was very uncommon to have mobile device holding music that you want to play wirelessly over bluetooth. With time the mobile device market got much bigger and the hardware required for the A2DP support got much cheaper and easier to implement in the media system software.
Right now most car makers are including bluetooth receiver that supports both HFP and A2DP as standard equipment. And even if it’s listed as option, most likely the hardware is in the car even if you didn’t pay for it. It’s only disabled with a configuration setting and can be enabled with a diagnostic interface (like in Audi MMI 3G and 3G+).

Possible Solution: I plugged my phone to the USB port in my car. I played a YouTube video and the music came out of of my car's speakers as expected. What I did not expect is that when I unplugged the cord, I played other YouTube videos and they played in my car without the cable. Somehow the cable connection had forced the car to recognize the Bluetooth connection between it and the phone. As I said before, I unplugged the cord and no longer do I need to use the cable for it to work; they connect wirelessly via Bluetooth now. I have a Nissan SV 2015 and a LG Q7+. I might make a video only if I get enough requests for it.

My problem is that both music streaming and phone calls were working for 2 months then all of a sudden, the music won't play thru my car's speakers via bluetooth. What's the issue with that?

Witam , od niedawna jestem posiadaczem audi s5 z 2008 roku. Ma auto nawigacje , system glosnikow bang and olufsen , w schowku mam tez taki kabel AMI chyba on sie nazywal. Wyszukalem ze jak kupie sobie BT na usb , albo na ten kabel AMI wszystko bedzie dzialalo , niestety nie dziala. Czy powinienem pojechac z tym do Audi czy co z tym zrobic bo juz mnie to draznic powoli zaczyna. W sieci bardzo malo konkretnych odpowiedzi na ten temat , widze ze Ty swietnie jestes obeznany w temacie moze bedziesz potrafil cos podpowiedziec. Probowalem tez uruchamiac to zielone ukryte menu niestety nie da sie go u mnie uruchomic.
