Area 51 Missing on GPS!

I recently downloaded a fine AFCAD for Area 51. After I installed it, as usual, I adjusted everything. On my test flight from KLAS to KGBL (the AP designator used), I could not see the AP or glide path on the GPS 500. Howerver, my panel has a built-in GPS and it shows up fine. On the GPS 500, it shows the flight path but no AP/glide path. Can I add an AP to FS2004? I have rebuilt existing AP's but have never just added one to and area with NO AP. Per realworld, this AP has Rwy 34L/14R at 18000 ft. 34R/14L is 11500.

Thanks

try adding it to fs9

Let's see....I downloaded it, added to FS9, added to scenery, added Comm's, added ILS, added tower, added designators. Yep, I added it to FS9. Now what did YOU have in mind? Great answer, but leaves a lot of info out!
