[Android Central Question]

The navigation works fine, but I haven't found a way to listen to the radio while using it. I have a long trip coming up and do not want to give up my music. Is there some setting that needs to be changed on the phone or the car's system? I have a Samsung S7.

This is definitely on the car side. The vehicle probably only allows one input to be selected at a time (most do) so it's an either/or situation.

I would just cache music to my phone and listen to that while driving. In fact - I've done just that on a recent trip.

Unless your car natively supports Auto. If it doesn't, then your car can only stream audio from the phone when that input is selected and cannot mix radio with navigation prompts. You'd have to stream the FM station through your phone for that to work (which the S7 can, you just need a radio app and to have headphones plugged in to act as an antenna).

Next Radio will stream most, or all, of your local stations. (It costs mobile data, but if you have enough, it's the way I do it - Maps and Next Radio work fine together.)
