I have the Dakota and really like it for my rides. I used it prior for our hikes and when I got in to biking it works great. If you use the turn by turn mode it should work for you. There are several maps available that you want, either from places like garmin or there are some free sites. I also have a newer nuvi(3490) and its about the size of an iphone 5. The dakota is ANT capable if you decide you need that. I would add that I think the nuvi is bulkier than the Dakota. The edge is a great product but the dakota is very versitle and bike friendly.
