Voice Command Not Working
Since the voice command has very limited usefulness, we haven't used it in years. Nonetheless, you can use it to dial phone numbers, so I tried using it today to no avail. While the car is running and the Command screen is on (playing a CD), I tried pulling the stalk toward myself, but it doesn't "beep." Hence, it doesn't respond to any commands. I checked all the fuses and they are all fine.
Any ideas? Thanks.

Mine died some time during the previous owners time, but he never used it so did not know.
I have been told I need to buy a new module, but have not bit the bullet yet. (ebay module is the same as the diagnostic fee, so I am still just guessing)

My 2008 GL does that same. (I have heard the module is essentially the same).

There is a write-up somewhere that tell you how to add it, so that would show where the module is.
DTB P-B-82.70/675 released 2/09 MY08 221 & 219 produced between 5/1/07 - 11/30/07 defective unit installed at production (hardware error), replace CU. Check your PM.

Any chance this would apply to a X164 in the same time period.
I am very sure the hardware module is the same (even if the SW is slightly different)
164.822 does have same VCS CU and part # is current but no notes in EPC (i.e.: applicable bulletin) 82.70/675 only applies to 211 & 219.
