SYNC 3 NAVIGATION HAS NO VOICE COMMANDS AFTER UPDATE

[dext]

I recently updated the software and maps for SYNC 3 and was happy that all was working ok, or so I thought.

Now I've discovered that the voice commands no longer work for navigation.

The Navigation works ok when using the touch screen and the voice commands still work for phone, USB. & DAB but if I use any voice commands for Navigation it just gives a beep as if I have used a wrong command.

 

I want to try a master reset but not if it means it will revert back to the old software and maps.

I know it gets rid of all stored info such as phone contacts and calls, radio presets, Navigation saved addresses etc but does anyone know if it will also take it back to the old software and maps or will it just reset my personal setting and leave software and maps intact ?
