I have a 2014 BMW 3 series and I am experiencing lagging issues through Bluetooth music streaming via my iPhone 7 Plus / Apple Music IOS 11.2.1

My phone is an iPhone 7 Plus running IOS 11.2.1

I had no issue when running IOS 10

Trouble shooting I have completed is as follows:

• deleting the Bluetooth connection to both the car and the phone

• deleted all music

• Hard reset the phone and network reset

• updated bmw software to the lastest version on the 4th December 2017

There is no issue when the USB Cable is connected to the car
