Voice Control with new bluetooth Module

HI,

Had upgraded my rSAP bluetooth module from 5N0 035 730B to 3C8035730B so that I can get HFP and AD2P.

The change was a success but i realised the following:-

My existing columbus had voice command where i can switch from radio to map to navigation, etc which can be activated by the top right button on the HU and also via the left steering wheel scroller.

After the Phone module upgrade, the wheel scroller on steering only do voice command on the phone function but not the rest. Voice command via the top right button on columbus still work.

Was wondering if anyone encounter this and had the solution. thanks
