How do I mount a remote folder to the "iMac" window in finder?

I am trying to set-up my Mac to automatically watch and mount the remote folder on my NAS using:

Currently, I have it set up to connect to //NAS/media as a log in item and "media" shows up in Finder in the main iMac window.

What should auto_master or auto_nas look like to get the mount to show up in the same way so I do not have to re-add all my media since PMS will see it as a different location? I have tried different things while I can get it to connect it is not listed in the same way.

My auto_master:
/ auto_nas

My auto_nas:
media -fstype=smbfs ://username:password@nas/media
