Questions about 4smarts Automotive FM Transmitter Media & Assist

I don't recommend the product, I ordered it, but on my 330XI E46 I keep hearing a whistling noise in the background, absolutely unusable.

I think so. But I am not sure. You still have a data sheet, maybe this can help you. I hope I was able to help you. https://www.4smarts.com/wp-content/uploads/2019/01/BDA_2play_MediaAssist-FM-Transmitter_84x96_web.pdf

Yes this should work :-)
