Is there a menu option for it in the MIB? Just go into the (function select you know where you find phone, media, radio etc) menu and see if you can find an option for carplay/mirrorlink/androidauto.
You don't need the phone plugged in to find it, its there, just try selecting it. If it says its not activated, you need to activate it at a dealer - by feeding them pound notes.
If the option isn't there at all, then you have a MIB unit before they had this feature available. 2015 Week 22 build onwards before you find it... so either a very late 15 plate or definitely a 65 onwards.
