Go here to download the dakota 20 manual.
Found good video on over veiw of it http://www.youtube.com/watch?v=p3z-rmNT4Xs
It shows switching between on road nav or offroad. So it looks like it does on road navigation. I just ordered a refurb from Walmart as that was the cheapest I could find online. I wil have mine next monday or tuesday. I can let you know for sure when I get mine. Cost with tax was 172.
Dont forget you will need to ad maps. The base map on garmin gps units is worthless (high end handhelds come with maps).I already have topo USA 100K for it. You need something like that which has all the roads on it to do street navigation. I had an old Etrex forget which model and it could do street nav but not near as good as a dedicated car gps. Car gps units are so cheap I would just get one of those too. They have the Nuvi models on sale at buy.com sometimes for around 50 bucks and they come with North america maps installed. Thats USA and canada.
