Ok ,

I have opened center console and checked to see if the pairing button cable is loose / disconnected etc took the negative battery cable off / reboot etc , changed to another ulf ( though still same generation) , etc check the fuse box ... And simply the process as in the manual (BMW) to pair phone etc did not work

was told by another member to pair via intravee . I.e assign a key to bluetooth ... And still no joy ...

I have DVD nav mk iv , ulf gen 4 , with intravee 2 with firm ware 6.01
