Glideslope with garmin 420

[billnaz]

I don't get waas derived GS depiction on the HSI from my Garmin 420 (gps com-no vor). I thought I had the configuration correct per this forum, did I miss a setting? Other CDI, and AP functions work as expected.

Do you have an HS-34? You cannot get any glideslope data out of the 420 without this.

Yes HS34 is installed and functioning. Also D100, AP74 and servos. All otherwise fully functional.

Is the 420 a 420W? The normal 420 does not output a glideslope. If it is a 420W, you need to make sure that you have vertical nav info turned on in the setup menu. Also, pretty sure the 420W only outputs vertical guidance after you have passed the IAF.

Waas, yes. Now that you mention it, I'm not sure if GS shows up after the FAF. With the start up test, no GS indication is provided though. Do you have the link to the garmin settings so I can double check my set up?
