Sound breaks up when direction are spoken

Turn unit on

Go to Tools.....Settings......Language

choose a language that ends with ( TTS )

the tts are the voice directions

At some point you may have switched the unit off before it completed it's start up dance. This will wipe out the voice file more often than not.

You will need use Garmin's web updater and re-install the file for the voice you want.

The "vocal directions" are a function of the Text-To-Speech, or TTS. When you are picking a voice for your unit, you will usually find 2 listings for each voice, and one of them will be designated TTS. Choose that one and your voice should give you spoken directions and street names.

If the mute is not checked, try plugging in a set of headphones. if you now hear sound, your internal speaker is blown. Please see this link:

you can set the types of roads you want the unit to follow. Highways or otherwise.

Hello, this possibly isn't a weather issue. All the voice combinations are stored locally on the local memory so their is no voice transmitted to GPS as in case of cell phone.

The issue is 'Text-to-speech' technology. Through in-built modules, it trys mimicing reading the english text as human's do and the sound is sometimes not natural. Its recognized as 'stuttering'

To isolate the issue, you can just select other language in the settings that is not TTS. It won't read the street names for you but you should receive a clean voice such as 'Take a left turn in 300 feet'

If you haven't registered your unit with Garmin, I suggest do it now at garmin.com. Then try for getting a latest software fix at the following location

Try changing the language to another voice instead of using Jill try the other one, then return see if it fixes

Click on the wrench tool button, then the picture of the sprockets which is system, then click the lips/mouth. Once there, you should be able to change the voice and text to English. Just click on one of the boxes to change it to your chosen language.
