Upgrade with Glideslope?
 

I have two kx155's in my plane. One with GS and one without. Can I add that GS board into the one without, or do I have to buy another 155 with GS?

KN 175 stand alone glide slope receiver is the answer. Fits anywhere behind the panel, a few wires to the KX 155 and the indicator, a GS antenae, and you're set.

Thank you.

I love this board, I was aking myself the same question> I just bough a Kx 155 No Glideslope and a 208 indicator and was thinking that I would have to buy a kx 155 with glide slope. I know I will need a 209 indicator are there other indicators that will work?
