For bicycle navigation I mainly use a Garmin device loaded with OpenStreetMap data covering all of D

I hope to learn it well enough to have all the safe bicycle routes loaded on my android device during my 7 day bicycle tour in Denmark in a few months...am I on the right track here? Or are my expectations out of line to believe that I can get a 100 square mile area of map data onto my phone? I really have no idea what is reasonable...And once I have a some mapped area loaded on a device, will I then be able to see my real time location as I travel?
Yes. You can install an application to use the OpenStreetMap data in off-line mode. The best application emerald club national car rental for Android emerald club national car rental to date that I know that works worldwide is OsmAnd, which is a free and open source application, but it comes also with a paid version to support the author. For the United Kingdom, however, there s a good application called CycleStreets — but as far as I know they don t provide non-UK data dumps for you to use in Denmark.
For bicycle navigation I mainly use a Garmin device loaded emerald club national car rental with OpenStreetMap data covering all of Denmark. For other uses i like to use OsmAnd for Android. OsmAnd does routing for bicycle, foot and car and so should cover your needs nicely. It will allow you to easily download a map covering all of Denmark (which should fit quite nicely on most phones) in one go. And yes, it can show you your current position emerald club national car rental at any time.
Less technical persons might want to look at MapsWithMe for Android, which is a much simpler app than OsmAnd, which also lets you download the entire map of Denmark (and other countries/areas) in one go.
