In terms of databases, you need the following for your region for SkyView to be fully functional:
-terrain (you downloaded this)
-base map (available from our website)
-aviation / obstacle databases (Jeppesen or Pocket FMS. Pocket FMS is a bit less expensive and has a bit better private airport information in Europe, but you can use either one)
Additionally, make sure that the firmware and the engine sensor definitions are up to date. Essentially, though, start at http://www.dynonavionics.com/docs/support_software_SkyView.html, go to the "Detailed SkyView Update Procedures", and read the whole page carefully.
