Update: I tried to boot up the display one more time, after about an hour or two, and it now works, and the update was successful. I am leaving this [post here in case anyone else experiences similar symptoms. I am somewhat concerned as to why this happened... Obviously, if whatever caused...

Tried to load the latest update file this morning (SkyView_16_0_8_US_Package_HDX1100_Dec02.duc , from 2 Dec), and it failed. It ran for about 4-5 minutes, (re booted once that I saw), and got to the point where it was cleaning databases, then screen went dark then light Grey but nothing else...

Yes, although I have been told the SV-GPS-2020 does a lot that a simple position-only GPS does not do. As I understand it, many items displayed on the Skyview HDX are calculated/generated inside the SV-GPS-2020. I'm not sure if the Skyview would be able to duplicate that functionality if the...

So - another solution would be - with the SV transponder, GPS (SV-GPS- 2020) and ADS-B in, using three of the five serial ports, you could install a Garmin GNC-355 as both a secondary COM transceiver AND a certified GPS navigator, and then still have one serial port left over for an N16/Vega...

Does that mean that current product is not hardware-capable of being software-upgradable? Let me rephrase. If at some point in the future, Dynon decided to add one or more features to the D3, is the current product capable of being so upgraded with only a software upgrade, or would it require...

Marc, Yes to both, that was my first assumption as well. Nathan at B&C was awesome in helping me diagnose and test it, but nothing was obvious. I had an LR3C-14, (Rev C), and B&C offers free upgrades to the LR3D-14 (Rev D), so I spoke with Nathan about getting it upgraded and bench-tested to...

Connected one remaining ground to aircraft ground, and still getting over voltage (up to 15.4 volts), out of alternator. When I wired up new high quality multimeter to same place that Dynon EMS was sampling voltage, I discovered that readings were within 0.1 volts of one another. So Dynon EMS is...

The only ground connected to battery ground is the case ground, (attached to a ground post on the SV-EMS-220 case). Does one of the DB-37 pins labeled Ground also need to be connected to aircraft ground? Dynon tech told me all these were for output of ground signal for individual engine sensors...

Well! That's an awesome idea. I'd have to change the wiring in the engine compartment, (and I'd have to find the yellow lead in the DB-37 for pin 2), but both pin 1 and pin 2 can be used for a voltage input. Perhaps I should add another widget to the HDX Screen hooked up to pin 2, and wire that...

Add a large horizontal glide slope deviation indicator to the HSI, so it looks like a regular CDI, instead of the little glide slope bar thing on the right edge.

Yes, I think I agree. That is where I was going next. I was going to check all the relevant wiring to the EMS. How (from what), does the EMS generate the voltage value? Pin 1 (red), on the D37F harness is connected to the battery bus, but this needs to be compared with ground. I would assume...

I have Skyview HDX with EMS-220 computer. Recently I had errratic voltage indications on my HDX. The voltage would intermittently jump up from it's normal 14.4-14.5 volts reading to 14.9-15.2, with associated audible "high voltage" warnings. At first this was intermittent. The high voltage...

I believe it would be a significant improvement in the usability of the system if they put a three-part segmented horizontal bar on the HSI depiction that came into view upon interception of the Glide slope, as the tiny GS indicator currently does. This is how the ILS indicators on the HSI...

Great! Even without details, that's significant, way better than just attitude, and GPS ground track, speed and altitude. Any hope that a future update might include more Terrain details? Like airfields and/or runway depictions? Is the D3 software programmable/upgradeable such that current...

Yes, I agree with your analysis and suppositions... Dynon?

Then how does it display what is called "Synthetic Vision", or perhaps I should say, what exactly do they mean when they say "Synthetic Vision"? Is this only a horizon line with blue for sky and green/brown for ground? The image presented in the user's guide: clearly shows terrain elevation...

Can the D3 display GPS position? Dies the synthetic vision display only show terrain height, or dies it also show other geographical features? If it has terrain data, and GPS lat/long, ... ?

I agree. The behavior as designed makes it ambiguous as to whether you have properly set up the avionics, or you just haven't flown into the basket yet. Somehow, that distinction shtould be obvious to the pilot! This would also have cleared up my confusion when I still had the VOR frequency in...

No... but I think I figured it out. At this particular airport, the VOR is located on the side of the Runway, 109.0, and the ILS is 109.9. I had VOR and ILS both dialed in the VAL2000. I had also set the ILS final approach course in the CDI course window. So, I think what may have happened is...

Yes, at home base... and I got A/P to fly it down to minimums.
