Xamarin Native UWP Design Pattern and Architecture

I'm doing a Xamarin Native Project, my goal is to have the three platforms : iOS, Android and UWP.

So I have 4 Projects : - PCL - Xamarin.iOS - Xamarin.Android - UWP

For Xamarin iOS and Xamarin Android I wan't to use the MVC pattern because it's the most used in these plateformes. But The UWP platform use the MVVM pattern as reference. The problem is to manage the navigation. How can I do to combine theses two patterns or may be I'm in the wrong way ?
