It doesn't matter, both are superseded (easily) by the TDS GTNxi.

I recently (with considerable effort) purchased and installed the RXP 530 and 75O into fsx /p3d. I agree with TDS vast superiority over the F1 but the main difference between TDS and RXP was the out of data AIRAC for the sim. This is actually a pretty huge plus for TDS but otherwise the units are on par with each other imo. A moot point maybe in 2025 but I had to mention it! 

Also I setup manual routes and multiple user waypoints for remote airports and points of interest in the 750s and annoyingly whenever there is an update in the TDS it wipes them all from memory. I've asked them for some way to export and import user data but got no reply. They have a great product but most of the user base will never see the advanced functions it has. 

So, if I understand correctly, the TDS one will use the current AIRAC. That's a given if I use the ultimate subscription. Will it also work with a Navdata-only subscription?

Yeah the data will work obviously just no charts

Thank you, Ryan. And airport layouts (i.e., runways and taxiways)? I have the RXP GTN for anything between FS9 and P3D, and they only show this for US airports.

Ahh you might get default flite charts without navigraph charts (North America only I think).  I'm just not sure if you can use navigraph data and at the same time use flite charts (default).

I can highly recommend the navigraph charts/data subscription.  Their standalone charts app is excellent and the charts work in VR via pop-up on the toolbar.

You could try a month and see if it's worth it.

Hello Russell,

Thank you for your assessment of the TDS GTNXi. At TDS Sim Software we care very much about responding to all our customers, we apologize if we may have missed a response to your question. We strive very highly to respond to all questions and listen to all requests/advice from customers.

We want to mention that updating the TDS GTNXi does NOT remove the flash memory, thus the stored flight plans/user waypoints. Those are stored in the PC Trainer's flash memory files, can be easily backed up, plus they get overwritten only when the PC Trainer gets updated, hence why if you update just the TDS GTNXi, nothing will get erased.

The TDS GTNXi is not just a regular GTN, there are many software differences, as a first, we are discussing of version 20.x of the GTNXi vs version 6.x of the legacy GTN. The internals of the products are much, much different, as well as the general user experience, performance, map detail, coloring and even the information displayed. It is beyond the scope of this post to start enumerating all changes, but they affect both the visual part of the units, as well as (most importantly), the actual navigation/flight planning and autopilot.

At TDS Sim Software, we are continually striving to improve the TDS GTNXi, both by resolving known issues as well as adding new features which will improve the product. More great things will come to the TDS GTNXi!

Hey sorry this was a while ago and I haven't upgraded since. There have been multiple problems with the install process itself as I wrote here.

I will always pass on the word that in 2025 your product has impressed me more than any other sophisticated real world addon gps. I have been using the most realistic Garmin addons in sims for over 10 years and this GTN gives me hope that realism is not dead in modern sims! 

The only issue I have is with the installers and the drm. Disabling a virus checker on a secure machine is never a good look! 

I might have another try at the latest update as the notification is driving me nuts anyway if you guarantee I won't lose my user data again.

Thank you for your kind words.

In regards to backing up user data, you can always post in the official TDS forum and we can point you to which folders need to be backed up as part of the flash memory. As long as you use the TDS GPS Manager to update only the TDS GTNXi Flight Sim, all should be fine even now.

To clarify some things: the TDS GTNXi does not come with an installer program in the traditional sense, the TDS GPS Manager is an innovative program which downloads and copies the files automatically, thus making the entire post purchase process very easy for potential customers. We do not ask users to disable the antivirus when running the TDS GPS Manager, this is a misconception, you just had to run the TDS GPS Manager as an admin.

At TDS Sim Software we strive very high to continually improve all aspects of our software so users will have a smooth experience.

Not sure what you mean... is there a difference?

I'm interested in how resource hungry they are. I expect the TDS to be more resource hungry but because I have not tried it I can't test and compare the 2. FPS is primary concern number one for me in flight sim.

When I do get it I will compare the two in exactly the same conditons to see how it affects performance but am interested to hear from anyone that has done this themselves.

OK, I understand the question... The TDS unit runs off the Garmin GTN Trainer, which may well execute on a separate core of your CPU...  I have not noticed any effect, but do not watch my fps counter, since I have set the sim to run at 50% monitor refresh (which in my case equals 30).

Does anybody know if there are any plans to integrate the default charts from MSFS 2024 into either of these products?

Navigraph integration sounds great, but that is yet another third party subscription to add functionality to a third party product.

In 2020, there was no chart option available, so the only way to get charts in the GTN units was the third-party route of Navigraph. This is no longer the case (unless the charts from the sim cannot be used outside of the built-in EFB. I am not familiar enough with the SDK to know if that is the case.)

I do not own either product and mainly fly GA aircraft in VR. Here is what I’ve been able to gather about the differences:

PMS

1. Provides current Navdata from MSFS 2024 without needing to pay for Navigraph subscription

2. Integrates with EFB in 2024

3. Weather radar

4. Don’t need to convert flight plans to Garmin file format

5. Less expensive

6. Can add custom airports not included in Navigraph

7. Can control Autopilot

8. Better integration into the sim??? Not sure about this one.

TDS

1. Better option if you are using the Garmin to train for IRL operation - using an actual Garmin not a simulation of one

2. Better option if you maintain a Navigraph subscription

I haven’t been able to discern why many (most?) people prefer the TDS. If you don’t want to pay for Navigraph and aren’t training for real world use, PMS appears to offer a number of advantages for use strictly within flight simming. But I would like to understand why people believe the TDS is better or if the conclusions above are wrong.

After my PMS subscrition ended I bought the TDI. 

Better in all regards on the account of it being a NxI unit. 

Only downside is that it can't read flightplans created in simbrief or the sim. 

You have to Insert them yourself.

I don't think that is an accurate statement if I understand it correctly.  On 21Jan 2025 TDS said this:
"As it is now, for the TDS GTNXi, both MSFS and XPlane, Simbrief flight plans can be imported. They have to be saved as GFP files from within Simbrief, then the TDS GTNXi will import them exactly like the real GTN Xi imports flight plans.

For the ease of use of the Simbrief system, the same folder path will be shared in between MSFS/XPlane flight plans".

If you have flown the RXP unit in P3D, the TDS unit operates and behaves exactly the same.  The PMS unit is not completely like the real unit.  Close, yes..  but not quite.  Some are OK with this.. I like having my Garmin avionics spot on. 🙂
