    Default Implement Original Layered Navigation to custom product collection

    I am trying to use the original Magento layered navigation instead of the one used in the below code for a custom product collection. The developer who wrote this code is no longer available and I don't know how to replace the custom layered navigation used in the below code with the original one.

    If anyone helps on this, very appreciated.

    Thanks

    PHP Code:
    class Designota_Catalogg_Block_Bestseller extends Mage_Catalog_Block_Product_List {
        
    /**
         * Retrieve loaded category collection
         *
         * @return Mage_Eav_Model_Entity_Collection_Abstract
         */
        
    protected function _getProductCollection()
        {
            if (
    is_null($this->_productCollection)) {
                
    $layer $this->getLayer();
                
    $layer->getCurrentCategory()->setIsAnchor(1);

                
    /* @var $layer Mage_Catalog_Model_Layer */
                
    if ($this->getShowRootCategory()) {
                    
    $this->setCategoryId(Mage::app()->getStore()->getRootCategoryId());
                }

                
    // if this is a product view page
                
    if (Mage::registry('product')) {
                    
    // get collection of categories this product is associated with
                    
    $categories Mage::registry('product')->getCategoryCollection()
                        ->
    setPage(11)
                        ->
    load();
                    
    // if the product is associated with any category
                    
    if ($categories->count()) {
                        
    // show products from this category
                        
    $this->setCategoryId(current($categories->getIterator()));
                    }
                }

                
    $origCategory null;
                if (
    $this->getCategoryId()) {
                    
    $category Mage::getModel('catalog/category')->load($this->getCategoryId());
                    if (
    $category->getId()) {
                        
    $origCategory $layer->getCurrentCategory();
                        
    $layer->setCurrentCategory($category);
                    }
                }
                
    $this->_productCollection $layer->getProductCollection();

                
    $this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

                if (
    $origCategory) {
                    
    $layer->setCurrentCategory($origCategory);
                }

                
    $this->_productCollection->addAttributeToFilter('fc_sales', array('gt' => 0));
                
    $this->_productCollection->addOrder('fc_sales');

                
    $this->_prepareFilterParams();

                
    $b $this->getLayout()->createBlock('catalog/layer_view')->setTemplate('catalog/layer/view.phtml');
                
    $this->getLayout()->getBlock('left')->append($b);
            }

            return 
    $this->_productCollection;
        }

        protected function 
    _prepareFilterParams() {

                    }
            }
            
    Mage::register('gan_filter_attributes'$attr);

            if ((
    $layerParams $request->getQuery()) && ! empty($layerParams)) {
                    foreach (
    $layerParams as $param => $value) {

                            }

                                    }
