The unit does not have a speaker. It will not talk to you.
I have had a Dakota 20 for two years. God help you if you choose the wrong language. I touched Chinese on the touch screen by accident. I had to contact tech help to get me back to English.
I have still been pretty happy with the unit. It is waterproof but be sure you have the battery cover on correctly!
I use both the Dakota and a car nav GPS in the car.
Not all roads are in either the Garmin map or car map database. Logging roads change each year. So while my car nav is sometimes handy in town, the Dakota is better for me in the boonies..I have a sense of where the nearest town is as it has a pretty good database of town names and geographic names. It wont tell me how to get there though..
I use topos from gpsfiledepot.com
But then my car GPS has told me to drive across a lake in the summer....
