How to call Channel MetaData fields in Navigation (channelNavRenderer.xsl)

Hi,

We want to show Custom Value coming from ChannelMetaData on Navigation. Currently channelName Value is appearing on Navigation Tree / Breadcrumb and these are controlling by channelNavRenderer.xsl. 

The ChannelMetaData Bean name is "navName", Instead of channelName we want to display this value. Kindly please help me on this.

ChannelMetaData Value:

<?xml version="1.0"?><qus_channel_metadata><id/><navName>Test Channel Name</thumbnail><contentAudit>Sat Feb 06 00:00:00 AST 2016</contentAudit><navOrder>true</navOrder></qus_channel_metadata>

Thanks

Jayaram
