On our home computer I set up X-Panel planing software and started designing the instrument and switch layout.
The Garmin G3X system was selected for several reasons:
- I had three Garmin instruments in my Globe Swift: a G400W navigator, a G695 moving map and a SL40 communications radio. The Garmin menu system was familiar.
- At two airshows I had the opportunity to compare Garmin equipment with Dynon and Grand Rapids. I thought Garmin had better screen colors and pixilation. Also at the time, Garmin had the only system with full IFR capability not requiring components from other vendors.
- There appeared to be little cost difference between vendors when pricing similar IFR systems.

Started ordering switches and other electronic components. I have found the DigiKey online catalog the easiest to navigate when hunting for parts by function and feature, rather than part number. I also started downloading and printing over 1100 pages of Garmin installation and operations manuals.
I have decided on Garmin for my 7 slider. I had my panel precut by Stein and bought the interconnect drawings. Did Stein do your harness? I was considering building my own harness, but like the thought of having them build one for me, though I’m using CB’ and not a VPX. For your switches, rheostates, wire, etc, did you go through digikey? I’m about to pull the trigger.
Hi Joseph,
Yes, Stein built most of my harness. I did all of the power wiring from the VPX plus the wiring for switches, lighting, etc. If you have the harness built for you, I suggest you know pretty closely where each LRU will be located so the harness wire lengths will be what you need.
I used some electrical components from Digikey and some from Mouser.
Good fortune with the build.

I am thinking of g3x for my rv7. Any tips / gotchas / info you can share ?
I amay still designing on paper and getting a bill of quantities together before ordering.
In the UK where I amust located the requirements are more onerous for ifr.
Ian,
I started to write you a list of all the decisions I had to make in selecting and assembling the panel, and it was unending. Only advice: plan, plan and do some more planning before cutting metal. As I have yet to put power to the panel, I don’t consider myself to be the best source of advice. Good luck.
I LOVE the pics and I LOVE bambas.com and I LOVE YOU!
