No I don't have a picture handy. I don't actually ahve a KX155. I'll describe what I do have. my plane came with a Terra 960 which is a nav/com/glideslope/indicator all in one. I moved that and the Narco 150 transponder from the left radio position to the right in what was the glove compartment.
I bought a Colins 251Com, a 351 Nav with a 351 glidespole receiver and a 351 indicator. I also bought a Garmin 155 and an annunciator panel. the Garmin 155 is a IFR certifiable GPS. All this for $3000 If i was doing it again today I'd probably not buy the Colins and replace that equipment with the King KX 155 that I suggested to you. It will cost more but after all the work it would have been a nicer outcome.
I also picked up a KMA20 Audio panel on Ebay for $200.
Forgot to say I bought the audio panel primarily for the marker beacon.
I installed all of this equipment to the left of the yoke. Starting at the top left is the annunciator panel with the 351 Indicator to the right. The 351 indiactor also serves as a left right indicator for the GPS. Under that is the GPS. Under the GPS is the KMA20 Audio panel. All of this brings us down to the bottom of the origanl panel. In a subpanel I fabricated which hangs directly under the GPS/KMA20 equipment is the Colins Com and Nav.
My thinking here is I wanted the GPS as high as I can get it so it fights my scan easier. At some point way doen the road I may replace the Garmin 155 with a Garmin 300 which is a direct replacement (there is another harness that must be added) then elminate the Colins stuff under the panel.
So what I end up with is 2 navs, 2 Coms, 2 glideslopes, 2 nav/glideslope indicators, one that serves as a left right indicator for the GPS. My GPS installation is also IFR certified.
Here is a half scale drawing that I used for planning purposes. The Yoke enters the panel just to the irght of the top of the GPS and the indicator. The original instrument locations and overlay are left untouched.
