The Garmin Nuvi 880 supports voice in both directions, to and from the user. The unit has voice navigation which commands you during the navigation, including preferred lanes. The preferred lane feature is not available in the budget products, but since this device is a middle-tier product, it is present. The speed compensation is a little bit questionable – it is certainly very good, but a little bit less than excellent.
You can also give voice commands to your Nuvi 880. For the voice recognition, the Nuvi 880 comes with a small unit, which is actually a “voice remote control.” You say “listen” to put the unit into listening mode and say “stop listening” to get it out of listening mode. In between, you can say something like “find nearest coffee shop” or “find nearest Chinese restaurant” and let Nuvi 880 find and display it for you. With the 6 million Points of Interest (POI) that are already loaded in the system, finding a location nearby does not seem to be a problem. And if you can’t, you can add your own. There are also proximity alerts for the POI.
