In cabin microfilter

Does anyone know if a 2000 Navigator has an in cabin microfilter? And where it is at? I assume it's buried behind the glove box.

Thanks, Mike

I found a reference to "15,000 Mile Service" checklist...
Replace Cabin Air Filter, if equipped.

On page 11 of the "recommended service intervals manual (https://web.msslib.dealerconnection.com/RightSite/getcontent/myfile.pdf?DMW_OBJECTID=09000c58800065b9)", but nothing in the service manual.

Thanks for the tid bit. I guess I'll call the dealer and they should be able to go off of my VIN and tell if it was equipped.
