Provided By MGL & Community 

The free Navidata (airports, waypoints, navaids, airspace, obstacles) file provided by MGL Avionics in collaboration with the MGL Avionics community is based on the (for now) inexpensive FAA NFD (National Flight Database) and the FAA DOF (Digital Obstacle File). This data is added to data from that includes many smaller airports not included in the NFD as well as some Canadian airports (but no Canadian airspace!), and exported from MGL Avionics Central (available to everyone here) approximately once a month and uploaded for free.

Odyssey/Voyager Gen 1 System Installation Instructions:

Copy file to SD card and using “Installation tasks”, install the file onto your EFIS.
Alternatively, copy file to SD card and use from SD card. This option can be used if you want to use a second, installed Navidata file. The G1 system will use the Navidata file installed on the SD card if such a file exists, even if a file has been installed.

Odyssey/Voyager Gen 2 System Installation Instructions:
If this is the only Navidata file you will be using:
Use “installation tasks” to install the Navidata file onto your EFIS.

If you would like to use more than one Navidata file:
The last letter of the “Navidata” word is a “region code” from “a” to “z”. Change this letter as required for your system, for example “Navidatb.ewd”. Install the file onto your system using “installation tasks”. Then select the desired Navidata file to be active using the region selection in your Nav selection softkey.
