I have an old eTrex that I use this way - I click a certain point on a map, where I want to go. eTrex will:

• calculate a route and start giving me directions based on the map I preloaded it (usually OpenStreetMap downloaded).
• While navigating it will tell me distance to end of route and each turn or waypoint and will recalculate the route if I wander too far.

My question is - Is there an app that does this for the iPhone?
Closest I found is Maps 3D Pro but it's missing some of the features I described.

Thanks!
