Just purchased and a few comments:
One of your earlier posts said we could have both male and female voice yet I only hear female (and the female is not very loud). Can we get the male voice as you state?
There are no settings (that I can find) - it's very important that when driving in a car (a noisy environment) that we have some form of volume control.
Please correct the voices or change the description of the app - I feel that I did not get my money's worth.
