Could better or easier to use

Using this for biking I had to plot out like every 15 miles to make sure it kept on the bike trail system from Cincinnati to DC even though the trail covers about 75% of the ride. It was set to biking but loved putting me on interstates, or would just put a line through an area with nothing road or trail-like. It assumes I want to carry my bike and supplies across a river? And...where do I get the turn-by-turn directions? Looked at the Elite aspects to this and it didnt indicate it allows that feature.
After getting flustered with this for 3 hours I realized Google Maps allows you to search specifically for a bike trail between two points. *sigh*
