I would love to be able to turn the different vocal cues on and off individually. The only option currently seems to be to get a cue 1/4 mile before the turn, 1/10 mile before the turn, and at the turn itself. The 1/10 mile warning always comes immediately after the 1/4 mile warning, making it useless and annoying, so I'd really like to be able to turn that one off!
