Since I've updated the IOS on my iPhone 5, I can no longer speed dial my favourites using the keypad on the Intellilink interface. I've tried removing the favourites from my phone and putting them back on, but this hasn't worked. I've also deleted and reinstalled the Bluetooth connection to the phone, but this hasn't worked either. The first phone number in my favourites comes up whichever number I press. Any ideas on how to fix this?
