6WB retrofit cluster - No nav on instrument display?

[noname]

Hi, So I have fitted a new 6WB cluster to a F32. 

Coded to the car and all is happy and working with no faults. 

I do not see the mini nav display (for your next direction etc) anymore in the cluster display. This used to function in the 6WA cluster that was removed. 

Can anyone through any light on this? It is a 2015 4-Series with the original NBT headunit.

Thanks in advance.
