After plugging the phone into the car, and playing a podcast or music from an app, a few minutes later, the music stops playing. Sometimes it just stops playing. Other times, it switches to a song in the Music.app that had not previously been played, queued, etc.
Orginal car had a Kenwood head unit with a USB port. Now the car is a BMW 328i with the stock system -- also hooked up via the iPhone's lightning port to the car's USB.
I've had this problem in two cars now, and it's only when playing via the iPhone 6 via the lightning to USB. When playing podcasts/music via Bluetooth, this never pops up as an issue, but I want it plugged in so that it charges, plus I get track info and album art on the car's screen via USB.
It's an intermittent problem, but seems to happen most often at the beginning of the day for the commute into work or on the way home.
I typically listen to podcasts in the car and it happens with both the native Apple Podcasts app, as well as Overcast. I've also had it when playing Pandora and even the Apple music app.
It's been happening quite awhile (over the course of owning two cars). Phone is currently running iOS 9.3.5, but has happened over the course of the last 2-3 major iOS upgrades.
I have tried multiple lightning cables, and as stated before, it's happened in multiple vehicles.
Any ideas to make it stop pausing/stopping/switching to a seemingly random song without having to resort to Bluetooth?
