I have been asked many times, how do i show my feed as a product feed on a module, so I have made this small tutorial for you here

<div>
<a target="_blank" href="/mambots/system/vmrss_v4/all_products.xml" class="mainlevel">
All Products</a>
</div>

<div>
<a target="_blank" href="/mambots/system/vmrss_v4/latest_products.xml" class="mainlevel">
Latest Products</a>
</div>

<div>
<a target="_blank" href="/mambots/system/vmrss_v4/featured_products.xml" class="mainlevel">
Featured Products</a>
</div>

<div>
<a target="_blank" href="/mambots/system/vmrss_v4/popular_products.xml" class="mainlevel">
Popular Products</a>
</div>

<div>
<a target="_blank" href="/mambots/system/vmrss_v4/custom_products.xml" class="mainlevel">
custom Products</a>
</div>

<div>
<a href="http://www.virtuemartfrooglefeed.com/virtuemart/froogle-feed-features.html" class="mainlevel">
View info about V4 feeds</a>
</div>

If you copy and paste that into code into your custom module as HTML, it will show your feed with the same CSS styling as your Main Menu links module.

Delete the bits you dont need, as I'm sure you wont need it all some part probably wont work, if you havent generated a feed yet.

All the best

PS
This is the same code i used for the Version V4 Feeds module in my right hand menu
