I love using the voice commands for my Sync system. I use it for everything , like tuning the radio, setting the temperature, making phone calls, and setting the navigation destination. Being able to 'chain' commands together is a real time saver and you get used to 'speaking sync' pretty fast. For example, saying 'Navigation, Destination, Street Address' is a great short cut to entering your destination into the system. The problem I have is no matter what I say, the system will not let me search for a POI by category. It doesn't seem to understand me. For example: I say 'Navigation, Destination, POI' to get to the POI screen. The next response to , 'Do you want to search by name or by category?' is where I can't seem to get Sync to understand. If I say 'by category' it will list the categories on the screen and ask which one I want to search. I have never been able to get past this screen. No matter what category I say, it says it didn't understand me. For example, I have tried the 'Automotive' category repeatedly. Never can get past it. If I touch the screen, it cancels the whole operation. Has anyone successfully used the Search navigation by POI category while moving using voice commands? What's the trick?
