Not according to Ray Catena Motor Car. It is only a factory option on the SUVs according to their service manager. The SUVs without the 5th and 6th button supposedly do not have the prewiring for it

If the vehicle was not ordered w/ voice control then it does not have a voice control wire harness i.e. not pre-wired for the installation. This is how M.B building them now, all models are not including pre-wiring for optional Telematics equipment unless specified on window sticker. Some retrofits have been released for certain items/models (nothing on the 164 yet)
A voice control harness is not available as a separate component at this time. If you want it added at this point you will have to find someone to make you a wire harness, purchase the connectors, possibly replace the steering column module, wire the vehicle as nec. and version code the vehicle. It would not hurt to have a M.B technician inspect your vehicle for possible pre-wiring sometimes it is there on mid range production vehicles.
Hope this helps,

The part number for the Voice Control Operating Manual for the 07 ML, R and GL is T-6515-9720-13. If the automobile has the option it should have been included.
An older version of the manual is available online here: http://www.whnet.com/4x4/vrm.html
