How to turn off that annoying prompt, which I hear several times when my GPS is coming to a turn? My laptop is connected to external speakers, I use it to listen to music and audio books, and I'd love to have my GPS silent. I don't need or want it to say anything or to make any noises. I figured out how to turn off speech prompts, but I do not know how to silence that "ding" thing. Anyone can help me?
