I have another one.
Phone: Samsung S7 (Android), bluetooth-connecting to Chrysler Uconnect, although minor internet digging seems to suggest that this is a Samsung issue, not a vehicle-that-it's-connected-to issue, because there are similar complaints about connecting Samsung phones to all sorts of different vehicles.
Issue: Bluetooth streaming audio, doesn't. Everything else seems to work. The phone sees the car and the car sees the phone, they're paired. Even the controls on the car that are meant to connect to the phone, work. You can skip to the next track or skip back to the previous track using the controls on the car ... but the music plays over the phone's own speaker, not over the car's speakers!
It has not always done this. It used to work. Nothing's changed in the car, so this is sure to be something changing on the Samsung side when they did a software update at some point.
Internet digging finds quite a few complaints of this nature, and a number of suggestions, but doing a few of the things that some people indicated had solved their problem did not solve it for me.

Bear in mind that I type at computers. What happens inside them when I do that, is outside my knowledge base.
