Like many others I play my music in my car via Bluetooth from my iphone (Currently iphone 8 but had same issue on others) using itunes, the music automatically starts playing though my in car unit once the car has started. I have a specific playlist I like to listen to i select the playlist and it plays no problem. However once I turn off the car the music stops mid tune and will pick up again from the same spot once I start up the car, all good so far, except that's where it goes wrong because the following tunes played are not from the selected playlist but just anything from the library usually in alphabetical order. So I then need to re-select the playlist and away we go again. Any ideas why?
