Sorry - only just seen this post.

The NG4 system is dependent on having the correct equipment other than the head unit and also must be VIN coded AND configured to the vehicle using Diagbox / Lexia.
The NG4 is designed to work with the MDS Service module, which is linked to the Microphone and the Head unit via the CAN system. So unless you got the hidden unit also from the car from behind the dash, you won't get it to work I'm afraid.
