GPS Tuner, developers of Outdoor Navigation, has released Turn by Turn Navigation for Windows Phone 7. Focusing on simplicity, Turn by Turn allows you to tap on a map point or search for an address, click on a pushpin and press the GO button to begin your journey.

Key features include:

  • Voice-Guided turn by turn Navigation with premium audio quality
  • Automatic Map rotation according to your heading POI and address search
  • Add POI-s or locations to Favorites
  • Route calculation based on Time or Distance using Traffic information
  • Bing Road and Hybrid Maps
  • Supporting Portrait and Landscape mode
  • Automatic re-routing if you miss a turn
  • Speed dependent Volume control
  • Driving and Walking directions
  • US and Metric units are supported

We liked Outdoor Navigation and if that's any indication, Turn by Turn Navigation should be a very nice app. There is a free trail version available that allows for routes up to twelve miles. The full version will run you $4.99.

You can find both here (opens Zune) at the Marketplace.
