Hi, anyone had the CarPlay retrofitted yet? I've been to my local dealer and they have checked that my car is compatible for the upgrade but they are unable to answer a few questions, I have an iPod connected to my USB, and don't want to loose this, will CarPlay work with Bluetooth? Or does it only work when connected via the USB, Is the voice button on the steering wheel activated with CarPlay and does this activate Siri? Many thanks in advance.
