Question about Pioneer DEH-X8700DAB incl. DAB antenna

I had already paired smartphones with iOS, Android and Win10Mobile to the radio. All devices harmonised well and the music playback could be controlled via the radio.
I have no experience with Spotify, but it depends on whether the app accepts commands from a Bluetooth device or not.
You can also test this with Bluetooth headphones.

don't know ,don't have Spotify!
