How Do You Turn Voices Off, But Keep The Alerts On

Dowload the nonTTS voice editor. Then copy a voice file from the garmin that doesn't speak street names. English_American_.vpm for example. If you pick one that speaks the street names then you can zap all of the commands and it'll still say street names. Weird but fun. 

Use the Voice editor to break apart the file into individual .wav files. Then use audacity to load the files in (I did this 20 at a time). Listen to each file, if it's a voice then hilight the waveform then click generate > silence and you'll see a straight line. Click export as .wav file and save each file with the same name to a new directory. The files that contain blips and bleeps just save the file to the new directory without editing. 

Go back to Voice editor and use it to recombine the files in the new directory to make a new .vpm file. Rename this file exactly the same as the one you are going to use such as English_American_.vpm and copy it back to the voices directory of the Garmin. That way you have silent navigation and blips for speedcams and POI's.

if u want no sound, take the garmin apart, when u do, find the speaker and clip one of the two wires that connect it. the garmins voice cannot be turned off otherwise. by cliping, not breaking. the wires, you can easily connect it again to hear voice
