Bluetooth Connection Issues

Hi Guys,

Got my Cooper S on Monday, paired galaxy note 4 via bluetooth, everything works fine, streams music etc.

When I come back to the car the phone wont re-connect, display on the car just says connecting but it never does.

Does anyone have any suggestions?

I took it to the dealer and they were very helpful but unable to fix it and want to book it in to re-load the software.

I hate leaving cars with dealers as I invariably go to pick the car up only to find a mark of some description on it!

If someone here is tech savvy and can help i'd really appreciate it.

Also what file format do I need for usb music as it doesnt like the apple codec.

Cheers
