Right now I'm using a flash drive in my cars usb port for music. I like the way I can control everything from the head unit / steering wheel. I would like to play Spotify from my Note 5 through my cars speakers and still be able to control from the head unit. Is this possible? I don't want to take apart anything. Would a bluetooth dongle work if I plug it into my cars usb port?

The other main reason I need to connect my phone to my speakers is using the navigation through speakers.

Thanks.

 

This seems like it would work cause I have both an aux and a usb port. What do you think?
