Wha..?? Do I need to buy ANOTHER GPS?

[dbwindom]

I thought I had researched my future SV system pretty well.  I'm building a VFR RV-8, but I want to "see and be seen" by ATC, and other aircraft, so invested in many IFR-type black boxes.   I recently received a big box of Dynon components and harnesses; SV-D1000, ADAHRS-20, EMS-220, GPS-250, BAT-320, XPNDR-261, ARINC-429, COM-25, A/P pitch, Intercom.  While in the preliminary stages of installing the harnesses, I noticed that there was only a black ground wire from the big connector for the ARINC unit.  After looking in the installation manual, it seems that I still need to have another GPS source fed into this ARINC…Is this true?  What is the GPS-250? Merely an antennae?  If I do not add any addition GPS inputs, what will I see on my SV?  Will I see a moving map?  Magenta line?  CDI?  Thanks in advance for helping me understand. :-?

What did you plan to interface to the SV via the ARINC-429?

AAflyer,

If you use only the GPS-250, you will have a full moving map on SkyView, assuming you purchased the mapping license (SV-MAP-270). This will give you free monthly databases in the USA, with airports, airspaces, obstacles, runways, terrain, roads, rivers, railroads, and more. You can look up frequencies, VOR's, NRST, etc.

This will allow full flight planning, direct-to's, and probably whatever else you expect too. This will give you a CDI on the PFD and a magenta line on the moving map.

It can also do weather if you purchase our SV-ADSB-470. You will get TIS traffic on the map with your transponder, and ADS-B traffic with the ADSB-470 module.

There are really only two things this combination doesn't get you:

1) Legal use of the GPS as primary IFR navigation. The FAA requires a certified navigator to be used, even in experimentals. None of our equipment is certified for this.

2) In 2020, you will need a certified GPS "puck" to meet the ADS-B out rules. The transponder you have is already fully certified for ADS-B out, but it needs a certified position source. Right now those are $4,000+, but we have full faith they will be much less expensive in 6 years. Right now, you will transmit your position uncertified, which gets you all the ADS-B services and is perfectly legal until 2020.

If you aren't planning on an IFR navigator in the plane, you can return the SV-ARINC-429. It's only used when you have something like a Garmin GNS-430 or GTN-650 in the plane.

Feel free to give our sales team a call if you have some more questions about your setup.

Thank you Mr. Dynon Support, for your prompt and fast response.
My in-depth research was completed last year sometime, and I probably concluded much of the same as you described; but since then I must have forgotten some of the important details.
I DID also buy the ADS-B…( I left it off the list of components on my first post) so TIS and Wx would be available. I had planned to buy the Nav-Map software after I complete the plane.
Thank you for your offer to take back the ARINC unit.  Perhaps after I finish my plane and it's initial "shake down & fly-off", I will be able to find an easily added certified GPS that I can add to my SkyView….if I find I need it. This level of support gives me great confidence in my decision to fly with Dynon.
Happy Landings.
