BMW vs. iOS 8.4 - disconnecting

I've tried the same steps you've done and haven't found a solution yet. What's maddening is this isn't happening 100% of the time. At this point, it looks like a bug that needs to be addressed whenever Apple gets around to it. As it stands, no reason to switch from Spotify if you can't enjoy your music in the car.

Same problem. iOS 8.4, BMW i3 with the most recent software updates.

Very frustrating, I hope it's fixed soon.

Same thing happening with me, but on a Mercedes Benz E Class. And mines happens only when I connect to it via a media interface cable, and the phone disconnects after every 1.5 minutes.

I Think it is some setting, but absolutely baffled why this only happens with streaming services from Apple and not others like spotify.

the problem isn't with Apple Music or your BMW necessarily. The same thing is happening in my X5 and I think the problem is this:

beats1 is live... when you listen to it on your iPhone, if you look at the timeline it shows something like this "--:--" meaning it has no end time. when you stream beats1 via Bluetooth to iDrive, you'll notice the time remaining starts to flip out, reset itself, then finally get stuck on 00:00 remaining.. i think iDrive is getting confused by the lack of time reported for these tracks streaming from beats1 and eventually just disconnects.

this doesn't happen when you stream a track from My Music, or through regular radio or pandora or spotify, because those services don't have a live radio and the tracks end times are reported correctly.

pretty sure sure this is the problem, but I don't know who would be responsible for a fix, Apple or BMW..

Everything works perfect in VW Golf IV 1.9 TDI via Jack input in AUX mode (Sony Explod car-audio equipment).

I am having the same disconnection issues and I don't even have a vehicle. Listening at home or work on wifi - and random loss of the stream.

That seems like a plausible explanation...hope it gets fixed soon

When I ride my bicycle, I use AirPlay and Bluetooth speaker (Philips). Works excellent. However I am back on the previous style of Music management, it means: I just buy good music tracks/albums and I will never enable Apple Music and iCloud Music Library again on any of my devices (they are still fruit-logo marked only, but I am not a fan now, I just have them currently, and yet).

8.4.1 fixes this. Whew!
