Hello,
We are pleased to announce that GTN V6.21 is now available as a software download to EAB customers with non-certified aircraft.
Please note that the software images linked on this page which format and auto-create SD cards are delivered to our dealer resource center as a Windows computer self extracting .exe file and are only usable on Windows computers. We apologize up front to Mac users.
As explained in the service bulletin, GTN V6.21 begins use of a new format of the Navigation database to support additional data. The database SD card for the current cycle downloaded using the FlyGarmin Windows installer contains both old (avtn_db.bin) and new (nav_db2.bin) formats, so you should just need to load the new format (the GTN will recognize the correct file) after updating with the V6.21 software. If you do not have a current copy of the Navigation database (Jepp or Garmin), wait to perform this software update since the new software cannot use the old format Navigation database and will remove that database if currently installed.
Note that the above paragraph mentions using the FlyGarmin Windows installer. If you use this database download tool, you have been receiving both versions of the navigation database since early this year.
Jeppesen has also recently started distributing both versions of the navigation database using its Windows tool if you have your subscription with them, but you must be using JDM Win 3.3.0.196 or later.
The FlyGarmin Mac database installer is not yet available, but when it is, it will also distribute both versions of the navigation database. The Jeppesen database update utility, JDM, also has a Mac version in development.
Service Bulletin 1657 and Software for Non-Certified Aircraft
A special non-certified aircraft service bulletin 1657 has been developed to provide the guidance for performing this upgrade. We encourage you to download the service bulletin first, read the instructions, and then determine if you still feel qualified to create the loader card(s) and perform the upgrade and installation verification. If not, the option of seeking assistance from a dealer is still available.
SB 1657, like the certified aircraft counterpart SB 1655, includes a GTN software upgrade, but also a GMA 35 boot block software upgrade (using a separate loader card) IF you have a GTN 750 installed in combination with a GMA 35 audio panel.
If you do not have a GMA 35 installed with a GTN 750, a single loader card is created and much of the service bulletin instructions are skipped that only apply to the GMA 35 software upgrade.
Follow the guidance in the service bulletin for obtaining a suitable blank SD card(s). Commerically available high quality 2G to 32G cards may be used.
For GTN only installations, you will download this single loader card image (from the above linked software download page) and create a single SD card to update the GTN to V6.21:
Service Bulletin 1657 - GTN 6XX/7XX Software Loader Image 006-B1367-36, Ver. 6.21, as of Apr 21, 2016, Download
If you have a GMA 35 audio panel installed with a GTN 7XX, you will download a second loader card image (from the above linked software download page) and create another separate SD card to update the GMA 35 Boot Block:
Service Bulletin 1657 - GMA Boot Block Software Loader Image 006-B2446-01, Ver. 4.20A, as of Sep 25, Download
Let us know if you have questions.
Thanks,
Steve
