zumo 450 or 550 Doesn't Have Any Sound

There are a few settings that can be checked if your automotive device does not have any sound. The first thing to check is that the volume or master volume is set to an audible level.

To Check the Volume or Master Volume:

1. Touch the Speaker button on left-side of the device
2. Use the + and - buttons on the left-side of the device to adjust the volume
   

If the master volume is turned up and the volume is still low, check the volume levels within the mixer to make sure they are set to an audible level.

To View the Device's Volume Levels within the Mixer:

1. Touch Tools (wrench icon)
2. Touch the Volume icon
3. Touch the speaker to the left or right to lower or raise the volume to the desired level for Navigation and/or Media
4. Touch and hold the back button

The volume level should now be set to the desired level.

If the device is still not providing spoken instructions at this point, you will need to change the voice to ensure that the preset voice is not faulty.

To Change the Voice Language:

1. Touch Tools (wrench icon)
2. Touch Locale
3. Touch Voice Language
4. Touch the desired language
5. Touch Ok

The device will now speak the selected language.

If changing the voice language resolves the issue, the language files may need to be updated on your device. For steps to do so, see  Missing or Corrupt Voice Files on an Automotive Device.
