I’ve tried to delete gns530 mod, start cold and dark, spawn on runaway, switch to gtn750 after take off, I even tried on Mooney and JustFlight Arrow III, it didn’t work, the map always freeze on the location where I opened it.
It worked fine on JustFlight Arrow before the update.
It just didn’t work for me.
Scorpion, THANK YOU for offering a lifetime option. This will be the way to go for me and I am looking forward to purchasing it! I am very happy that the roadblock to my support of the premium product has been resolved. 
I love your work!
Sorry again my mistake.
If you test the sim update 4, the current official release of the GTN is not working.
You have to wait for the new version from me.
Maybe I can publish a beta of the beta 
?
What’s not working in it?
I’m in the SU4 beta and seems fine to me… at least operating buttons and such
Maybe you have modified the file SvgAirplaneElement.js ?
Ah, yeah. I believe I changed diffAngle to angleDiff when you first posted about it as a fix. That would explain why it’s working
Looks like when they installed that nice new GTN750, they forgot to remove the protective film from the glass !!
At night its fine, so it NOT the display itself – it has to be undesirable (non real world), modeled reflection, on what should be non-reflective glass.
Now there are other issues but you will probably not see them and globaly that works if you modify this line of code.
So ONLY FOR THOSE TESTING THE SIM UPDATE 4:
File SvgAirplaneElement.js of the Mod line 223 replace “angleDiff” with “diffAngle”.
I really don’t understand why they changed this function name and, by the way, created a potential issue.
Ahah Exactly.
If you look at the picture, there are no reflections. One does not see the plane interior in the panel. So the material is non-reflective glass, like you describe it should be. The JF version does appear to have a protective glass at all.
Correct, no refection of Objects, but there is a reflection of overall abient light.
The brighter the cockpit, the more the B;lack of the display appears to lighten to a dark, or even medium gray.
Maybe its better described as a lack of Contract ratio.
True, different type of displays have different contrast ratios. Some of them have blacks that are rather gray, or uneven. TN panels are known for their high refresh rates, VA panels for their good contrast, IPS panels for their good color reproduction and background light bleed. Now the question is, what kind of panel is the one in GTN750? As far as I’ve understood, there rarely is only one specification when it comes to aviation navigation. These specifications for choice of materials and components tend to change between time periods, too, as technology progresses.
You appear to know your LCD panel technology … as do I.
I have never seen a Real World GTN750, but I would assume back then they were designed, they use a TTFN panel, with either CCFL tubes, or more recently, LED backlighting.
All technical discussions aside, the bottom line is that in the Carenado plane, the Display gets “washed out” in sunlight, which it does not do in other aircraft, and which it most likely does not do in Real World.
It’s a simulator, and Carenado has control over this apparent “Washed Out” effect.
My take is that it is far too washed out, which is not something I would want in RL, or in a Sim.
On a side, I would note that Carenado, do have a habit of making their LCD displays “washed out”, (ie LED/LCD Status displays, Transponders, DME, AP etc etc).
Bottom line – Carenado, please do not overdo the “sunlight” “wash out” simulated effect !!
(Cool that you can do it – but sometimes less is more !)
Physical & Performance:
Unit dimensions, WxHxD: 6.25"W x 6.00"H x 11.25"D (15.9 x 15.2 x 28.6 cm)
Display resolution, WxH: 600 x 708 pixels
Display type: Color TFT LCD; sunlight readable
Weight: 9.3 lb (4.24 kg)
The GTN750xi has a substantially better 834 pixels (W) x 986 pixels (H) dsplay.
Just putting it out there I installed both free and premium into the Seneca update and all went fine with both from the EFB. Nice Job!
P.S. the Metar token was a PIA but got it! LOL
There you go “Color TFT” which are adequately Sunlight readable (at least when new, and the CCFL light has not aged !!)
Upgrading those older TFT displays to a LED Backlight, breaths a new, significantly brighter life into them.
No doubt a complex and regulation involved thing to do with Avionic Electronics !!
There are upgrade programs and deals …
Ironically, at this exact time, I must get off this forum, and update an Industrial TFT LCD display from a dim CCFL (or blown inverter) , to a bright LED backlight
Changed the js file per instruction, now the map works fine, thank you again for this great mod!
