BROKEN

This app. no longer works since IOS 6.1 It used to have turn by turn VOICE navigation but now the VOICE no longer works!!! I have uninstalled & reinstalled several times! And why did I have to keep adjusting the volume for every address I wanted directions to in order to hear it? Leave the volume so it always stays at the same level! It is dangerous to have to keep finding & adjusting the volume while driving! DEVELOPERS U NEED GET ON THE BALL & FIX THESE PROBLEMS W/ UR APP!!!
