I purchased my TT a wile back and had it updated in November 2013. I have not used it until yesterday and noticed that there's no sound when i make screen selections. Voice is on and gives directions, but no touch sound like a "bleep". It may soumd stupid, but i'm not sure if there should be a sound when you touch the icons, cannot remember if it did. Have searched the internet, but cannot find an answer. If it should make a sound, how can i fix it, had already done a reset or two with no difference.
