Replace Cabin Filter for 2000 Toyota Sienna CE 6 Cyl 3.0L

I already open the entire cover infont of passenger seat but not..I wonder if located on the center, under the car stereo...

Since then i went to NAPA home, that is their site, entered your info. they do not list a cabin filter for this van! 2002 i think was the first year listed. IF it had one so would NAPA.
