Is there a way to take a HUD modeled in one of the other aircraft, and make it work in the Citation Longitude. Been waiting 3 YEARS and those that can, apparently have no interest in doing it, so I thought I’d try to do it myself. Is this possible?
Personal Comments and Observations
Only one S/N actually has it and it’s only coming online this year. It’s not exactly a missing feature present on the jet in volume.

Not quite sure to what you are referring when you say “only one S/N”. As far as I know in MSFS 2020 there are no S/N s, and IRL the HUD came out for the Longitude in 2017. Many IRL do not use seat belts, that doesn’t prevent the manufacturer from installing a fully functional seat belt safety system in every vehicle.
My point is, can I do this myself. Is there someone that can point me in the right direction?
There is only one Longitude that opted for installation - that meaning s/n for serial number. It’s not a standard offering and in the spirit of fidelity, MS-Asobo would have to gain access to it for modeling. That would mean Cessna and more importantly, the private client who owns the jet, would have to grant permission. That’s big level of effort to get a one-off STC.
Can you do it? More likely not because you probably need access to the jet’s artwork files, which are encrypted as are all Premium Deluxe aircraft in the sim.
Do you mean the jet in real life?
Yes, the jet in real life. Because modeling the HUD is more than just coding a HUD to fill the display.
Sorry don’t want to sound mean or dumb but can’t you copy/paste the HUD from the Boeing Dreamliner in the meantime?
Seems very similar:
How would it affect the Licensing agreement with Cessna? It’s not an accurate representation of the HUD, which is highly integrated with the G5000 and the symbology and other aspects are reflective of the Garmin system’s PFD. The HUD of a Rockwell Collins (787) system is different.
No offense or to be mean or anything, but I just don’t understand how Microsoft was able to get the license for some of the plane and not all off it.
A License doesn’t cover all aspects of an aircraft. Over time, STCs and other formal modifications are created and applied to the original design. The License one negotiated in 2019-2020 may only cover certain recreation/simulation/branding aspects.
Again, this is not a widely used feature. Despite being announced in 2017, it’s now six years later, and only one customer has opted for it. Literally it is not representative of the Longitude jet at large.
As far as I know most of the C700s irl do not have a HUD so it would be unrealistic to add it. I believe it is an option for the plane but operators have opted not to have it.
Also when you enable visuals + path cue on PFD you get what HUD shows 
The IRL HUD for the C700 Longitude was not certified by the FAA for use and was installed in no aircraft at all until a couple months ago. It has only extremely recently been certified and is now available as a customer option. At the time we overhauled the Longitude it was not certified and had no timetable for being certified nor any manufacturer documentation.
Superficially they look similar but the units are extremely different in operation.
Since the HUD unit has now been certified, it would most likely be possible to get the documentation to build it (we haven’t specifically asked), but unfortunately resources have moved on to other projects at this time and it is no small thing to build (probably a good 200-400 person-hours minimum). Perhaps some time in the future, though.

Then why was it modeled into the game?
There are many items in both Asobo and Third Party planes that are INOP. Tell you what, feel free to use the Support Link at the top of every forum page to put your feedback directly to Asobo. There’s an option in the ticket to do so.

Seems to be a separate gadget altogether
Short YouTube video about it
At the time of the original modeling, the IRL plane was still in the prototype phase (the first C700 hadn’t been delivered yet, it’s only a couple years old, not 2017 as another poster claimed) and the HUD was intended to be available at aircraft launch, therefore it was modeled into the plane. Unfortunately, the FAA certification for the plane did not also include the HUD, so this was just a case of unfortunate timing for everyone.
Makes sense. According to Wikipedia, the aircraft was announced on may 2012, first flight on October 8th, 2016, and certified on September 2019.
I also wish the HUD in the FS2000 Longitude was operational. I spent many years working as the lead engineer (now retired) for the GHD2100 HUD at Garmin. I purchased the highest level FS2000 software package just to see it and use it. It’s disappointing to see it stowed but not deploy. But, If a third party does it for FS2000, I would be more disappointed to see it done incorrectly. Contact me if anyone needs help to do it right.

I am completely sympathetic. The only reason I upgraded from Standard to Premium Deluxe was to gain access to the Citation Longitude. To put it mildly, was disappointed the HUD system is INOP. And, unlike X-Plane — where I flew for more than a decade — with MSFS I have zero ability to switch into a Gulfstream 550 and use its excellent HUD (in other words, the business jet presence is disappointing, despite the CJ4 and C700 being excellently developed in many ways).
I don’t care if the HUD is in 1 or 1000 of these jets, if MSFT is going to limit the number of high-functioning business jets, then at this point in the development cycle, I agree with the OP and think more should be done. I also think the assertion that Cessna couldn’t provide everything MSFT would need is patently wrong. Cessna has demo equipment with the HUD option for prospective sales and previous testing and certification. Heck, If needed, send a team to Kansas and get ‘er done. I’ve contributed my $100 towards the work by purchasing the title.
