There is no way to bind ActionBar to ICommands with MvvmCross. But you can use a simple trick and call into your ICommands from the activity when a button on ActionBar is pressed.

public override bool OnCreateOptionsMenu(IMenu menu)
{
    this.MenuInflater.Inflate(Resource.Menu.QuoteDetails, menu);

    m_MenuItem_EditQuote = menu.FindItem(Resource.Id.menu_EditQuote);
    m_MenuItem_EditQuote.SetVisible(ViewModel.CanEdit);

    return true;
}

public override bool OnOptionsItemSelected(IMenuItem item)
{
    switch (item.ItemId)
    {

        case Resource.Id.menu_EditQuote:

            ViewModel.EditQuoteCommand.Execute(null);
            return true;

        case Resource.Id.menu_ViewQuote:

            ViewModel.DownloadQuoteCommand.Execute(null);
            return true;

        case Resource.Id.menu_EmailQuote:

            ViewModel.EmailQuoteCommand.Execute(null);
            return true;

        default:
            return base.OnOptionsItemSelected(item);
    }
}
