Any suggestions for an Android app for a smart phone (Droid Razr in my case) aimed a biking that I can use for cycling mapped century routes?

I am looking for an app that displays the route, gives direction prompts (preferably audible as well as visual) and also displays and tracks current position on an elevation profile (which need not be on the same screen). Something that shows where I am in terms of horizontal and vertical location and where I am going. It the app displays other information - speed and distance for example - that's a bonus but there are plenty of cycle computer apps that provide that information.
