When attempting to use the voice command feature on your compatible Camper/RV, dezl, dezlCam, nuvi, or nuviCam device you may see a message that indicates that it is unavailable for your chosen language (e.g., "Voice Command support is not available for American English").
This can be caused by incorrect language settings, a missing file, or an incorrect map region. First, verify your device's voice and text languages are both set to a compatible Text-To-Speech language for speech recognition. If this doesn't restore functionality, try restoring the speech recognition file.
To restore the speech recognition file:
The download will start automatically. When the download completes, an "updates complete" message will appear near the top of the Garmin Express window.
If installing this file does not resolve the problem, you may have loaded only a region of mapping to your device during a map update. Run the map update again and choose full coverage for your continent. For example, if your device was preloaded with Europe, you'll need to install Full Coverage of Europe.
The only exceptions to this rule are the North American nuvi 800, 805, and 2460 series devices. Voice Command on the 800 and 805 series devices will work when either Full Coverage of North America or US & Canada are installed to the devices internal memory. The nuvi 2460 will allow you to update the maps through Garmin Express using a microSD card. All other North American devices that have voice command may only use voice command when Full Coverage of North America is installed.
Regardless of the model used, voice command will only work with mapping that was originally preloaded with the device. Not all features will work with voice command if you are using supplemental maps (e.g., European maps on a device purchased in North America).
