Condition
The message "Button vacant" appears when pressing the Push To Talk button on the steering wheel. In the telephone setup menu, the message "Voice operation cannot be activated" is displayed in the Sound Settings option.

Usually the issue occurs after replacing the Front Information Display Control Head (Headunit J523) or after
retrofitting the Speech Dialog System - Control Module J507.

Vehicles with Telephone Transceiver R36 (UHV) in combination with the Speech Dialog System - Control Module
J507 (SDS) are affected.

Technical Background
The Speech Dialog System Control Module J507 may interfere with the internal speech command function of the Telephone Transceiver R36. (The internal function was introduced in model year 2007.)

Production Solution
Not applicable.

Service
The Internal Speech Command function of the Telephone Transceiver R36 must be deactivated.

Change the second digit from the right of the Telephone Transceiver R36 - Coding (Addressword 77) to 0 (e.g. change 10910 to 10900).

A Reset via Headunit Adaptation channel 111 (set to 1) of the MMI system is necessary before verifying the proper function.
