Apple Music app, iOS 13.1.2, playing music from iPhone 6S over AVRCP Bluetooth on a Pioneer MVH-390BT aftermarket car stereo, autoplay and listing issues
I have a Pioneer MVH-390BT stereo in my car which allows easy navigation of the Music app, including "Recently Added", lists artists, albums, songs etc. over an AVRCP Bluetooth connection.
Since updating from iOS 12 to iOS 13.1.2 I can no longer navigate through the structure of the Apple Music app by pressing the search button on the head unit (it will occasionally get to "Music" but tends to get stuck there and I can no longer move on to "My Music" > "Artists" > "Recently Added" etc.). I had previously been able to do this over Bluetooth (AVRCP) and without being connected by a cable.
I noticed that on iOS 12, when initially connecting via Bluetooth, Apple Music would start playing the first song listed alphabetically, now on iOS 13 it plays a random track. It seems to do this without the app even being open, so in my case with an iPhone 6S when I open the phone to inspect which apps are running by double clicking the home button, the Music app is not there but a random song will be playing anyway. This, I suspect, might be Apple trying to find a way around the common complaint that the same song plays every time a user connects their devices. I also suspect that the random autoplay is somehow affecting the app from listing its contents successfully. Surely there could be a way to control if a song would be played or not when a connection is made?
I have done a factory reset on the head unit and a hard reset on my phone, forgotten the device in the Bluetooth settings.
I now regret upgrading to iOS 13 and I’m also considering swapping my Apple Music family subscription to Spotify as the head unit also supports that.
Any suggestions or similar problems out there?
Thanks for reading.
