[Solved] Find the source for topSiteMap

[Lonsrd]

I inherited a MOSS environment and I need to change the top navigation menu, I see that the navigation is using a RADMenu
<telerik:radmenu ID="TopNavMenu" runat="server" ExpandDelay="10" CollapseDelay="10"/>

But I can't find where its generating the menu from, I have checked SharePoint Navigation, fix links and no trace of sitemap. Please help me identify where the menu is being generated from so that I can be able to edit it.

Thanks
