How to implement MVVM with NavigationService in Silverlight 4?

Question

I'm new to Silverlight and NavigationService. I try to adopt them with MVVM. I found this link but it don't work for me, may be I do something wrong. (It don't has sample solution)

I want to know, are there any website/example out there?
