Give your nuvi 3790 a name such as “I love you”, and it will recognise when you're talking to it.
Simply speak the words you see on the screen or certain commands, such as "Where To?" or "Volume" and listen to the voice prompt before your next command. A built-in speaker is included on the back of nuvi that allows you to hear directions while walking.
NOTE: Voice Command feature currently supports British English only. It is not available in all languages or regions.
