I think wht's happening here is, as basic BT function is built into the L7 Entry HU, if u have 6NH then there's no combox. If u have nav pro then, as it doesn't have built-in BT, if u have 6NH then it'll come with a combox with some features disabled.
For the combination of L7 Entry + 6NK/NL, the BT hardware is not present in the headunit as a combox is present, hence a different HU p/n is present.
