Bluetooth won't connect after iOS 9.2.1
Since upgrading to iOS 9.2.1 I have been unable to pair my iPhone 5 to BMW's Bluetooth communication system for hands free telephone calls. I have turned the phone off and back on, toggled Bluetooth off & on, deleted the pairing and re-tried, disabled Siri and have reset all networks, all to no avail. Bluetooth is working fine in my wife's Ford and streaming to a soundbar also works; it's just the BMW connection.
I have read that Apple has upgraded its Bluetooth protocol ahead of others, which may require software upgrades to certain other devices. Whilst I understand software upgrades are possible in BMWs manufactured since 2010, this doesn't help me with my 2008 vehicle (3 series). I'm hoping iOS 9.3 will fix this problem as I am not willing to pay for a BMW technician to alter their inbuilt software to match Apple's (nor should I have to buy a new car to match my phone!). Can anyone shed any light on this issue? I'm based in the UK.
iPhone 5, iOS 9.2.1
