The voice recognition in my car stopped working a few days ago. When trying to use the voice recognition to set a navigation point, the car would initially saying it was processing the request and then state that voice recognition was not available (not the exact error language). At first, I didn't think much about it, thinking that either there was an issue with the Tesla server, or that there was an ATT issue. After two days, it dawned on me that this issue started right after I had the folding side mirrors retro-fitted to the car. So I called the SC to asked whether there was a connection between the folding mirror installation and the non-operation of the voice recognition. The SC told me no, but indicated that many people have called to report that the voice recognition is not operational, and that Tesla has a patch that they can push to the car to fix the problem. I haven't received the patch yet, so I don't know whether it actually does take care of the problem. But if you are experiencing problems with the operation of the voice recognition in the car, you may wish to contact Tesla to see whether you need to get the software patch.
