Nav data update

Recommended Posts

hi,

 

how will we be able to keep the nav data up to date ?

 

This is a must if we want to use it in our cocpits.

 

thanks

Since the gauge is based on the real Garmin trainer, the only way to keep the nav data up to date is to get a subscription to the Garmin data.

Or get an update whenever Garmin updates their GTN trainers.  You don't need to install it the new trainer (as it might not work with RXP or F1's version), instead you need to extract the data and copy the respective files to the new db folder.

 

PM me for details

ryan, do you know if the method of upgrading the database is the same as F1's method? where we replace some of the files in the db directory?

It is even easier! you don't have to replace your files, just point our GTN to the folder you've copied them:

 

edit/create a GTNDBFILE environment variable with the path to your DB file, like "C:\myfiles\my_new_avdb.bin

Wow, that's an even better implementation to update the nav database. But my understanding that there are more than 1 db files... such as taxi ways, and terrain db as well... what about those?

It's easy! 

 

GTNSIMPATH environment variable to set the path to your trainer, typically:

C:\Program Files (x86)\Garmin\GTN Trainer\GTN\sys\sim

 

GTNSIMDATA environment variable to set the path to your files, typically:

C:\ProgramData\Garmin\GTN Trainer Data\

 

GTNDBFILE environment variable to set the database file only, typically:

C:\ProgramData\Garmin\GTN Trainer Data\DB\xxxxxx.bin

 

This way, you can override path to the other db files (obstacle, baseman, safetaxi etc...) and separately override path to the aviation database.

There's a lot of people that keep asking me how to update the NAV data for the Reality XP.   This is possible.   It works for whether it is a GNS (430/530) or GTN-series GPS.  Doesn't matter.

The GTN uses a Garmin database. 

This is not compatible with Navigraph. 

There are actually several databases that can be updated.

NAV = avtn_WW_db.bin

Safe Taxi = safetaxi.bin

Terrain = AMRN.dat

BaseMap = bmap.bin

Obstacles = ???

 

These can be found in C:\ProgramData\Garmin\GTN Trainer\db\  (just replace the drive letter to where it was installed)

 

If you have a subscription with Garmin (whether you have a GNS430/530 or GTN-series GPS in your ACTUAL plane) - these files can be easily copied to the above directory.   You will need to RENAME avtn_db.bin --> avtn_WW_db.bin

 

Terrain will also have to be RENAMED (trn.dat --> AMRN.dat)

 

Don't forget about changing the ATTRIBUTES.  The Garmin files come in as (RASH).  These need to be changed to (A)rchive

 

Just for the sake of clarity, the latest Trainer_2.00.3 files are named somewhat differently. For example, the world-wide terrain database is now named:

C:\Trainer\CommonAppData\Garmin\GTN Trainer\db\006-D2659-00.dat

We need to rename the existing AMRN.dat to something like orgAMRN.dat, then rename the copy of 006-D2659-00.dat to AMRN.dat... 

 

I hope that helps

Hi, i´ve an Garmin 430 subscription and I found the .BIN file for my database (USA&Latin America) C:\ProgramData\Jeppesen\Jdm\.jsum\download\dgrm72_1711_F2889A27.BIN.
I've been trying to update my RXP Database but it crashes the Garmin trainer.

My trainer has the path C:\Program Files (x86)\Garmin\GNS Trainer\GNS\db and inside this folder i've a file worldwide.bin that's the database (Cycle 1511).

I changed the dgrm72_1711_F2889A27.BIN to worldwide.BIN but the Garmin trainer and P3D GNS430 still crashes.

I double checked the Atributes and both files are Archive.

What i'm doing wrong?

Thanks!

I believe that the file you are looking for is called avtn_db.bin.

It is likely contained inside the bin file you are looking at..

I've sent you a PM

Hi,

First, you don't have to rename/overwrite your existing DB file for experimenting a new one: our solution provides the means for you to specifically configure the path to different trainer data, including the DB specifically. It is in the User's Manual (environment variables).

Then, the  .BIN file you've got is probably a disk image, not a file. The DB has to be 'extracted' out of the image. In most case, a simple HEX editor which shows you the content and can erase mouse-selected areas will suffice.

Comparing a working file, with your .BIN image, in an HEX editor will reveal what you need to remove from the start of the file easily. The byte amount to remove is also a multiple of 16 most of the time.

Never updated charts before. The related navdata is located in ....../program data/garmin/gtn trainer/db

What is the filename for the charts?

Hi,

In previous trainers, the charts where in the card file (it is just a disk image, rename to .iso and mount the image to see the content). With GTN trainer 6.41, there is no card anymore and the files are installed as-is into:

"C:\ProgramData\Garmin\Trainers\Databases".

The charts files are:

  • fc_tpc\fc_tpc.dat which looks like the "charts directory"
  • fc_tpc\charts\*.fca which are the per-airport charts themselves.

NB: trainer 6.41 has more recent charts but misses the Canadian charts found in trainer 6.21.

Thank you for the reply RXP - have you tested doing an update?   Curious on the steps in 6.41......

Can we just delete all the fc_tpc charts and fc_tpc.dat files?   What OTHER files need to come off the Garmin data card from my plane?    Or do I just do a full replace on anything and everything it wants to EXCEPT move the Charts to fc_tpc folder?

Thanks,

-Brendan

I really can't tell, but should you have the data, provided you make a backup of the existing in case, you might want to try out and let us know?

Initial signs are good -  it's running, charts load (seemingly correct including departures) and the SIDS and STARS are loading correctly.  Maybe a cleaner way, ut here's what I did:

1. Copied the entire contents of my GTN750 card (all the files in the root folder) to the C:\ProgramData\Garmin\Trainers\Databases folder, and OVERWRITE originals.

2. Copied DATACARD\ldr_sys CONTENTS (two files)  to the C:\ProgramData\Garmin\Trainers\Databases folder, and OVERWRITE originals

3. Copied DATACARD\active\fc_tpc FOLDER to C:\ProgramData\Garmin\Trainers\Databases\fc_tpc folder, and OVERWRITE originals.

Looks good so far, hope this helps others.

Ok so I am not a computer programmer and dont even know how to create a .bin file. I have the GTN 750 for xplane but the DB its running is old I think its 1605 or something like that. 

 

Whats the easiest way for me to update that? I thought of paying 149 to get a single dataset from garmin however, I dont want to buy it and then not be able to figure out how to use it. You guys are talking WAY above my head. I can go all day in VBA and SQL but .bin files, hexadecimal editors, creating images from .bin files...I have no clue. Can someone tell me the easiest way?

Hi nigelmcelwee, 

The installation is basically first backing up your existing files and then copying/overwriting them as the new files. crazedpilot gave a great outline, above. I successfully updated the nav data for Garmin Trainer 6.41.1. It won't go wrong for you.
