Converting JNX to raster IMG

**Eyelet99** · 2nd April 2019, 03:26 PM

Yes I have tried your batch conversion script but the CMD just took me back to the jnx2img folder without running:

Microsoft Windows [Version 10.0.17134.648]
(c) 2018 Microsoft Corporation. All rights reserved.

C:\>cd\jnx2img

C:\jnx2img>batch_convert.cmd "c:\maps-jnx" "c:\Maps-img"

C:\jnx2img>for %i in ("c:\*.jnx") do call jnx2img.cmd "%i" "c:\%~ni.img"

C:\jnx2img>

Also, when I created the three IMGs which had the same MAPIDs, I did run the jnx2img.cmd three times in succession.

Hello,

To have batch I modified the file jnx2img.cmd see the post #113

To run the batch script correctly, the folder names should be ended with backslash like this:
C:\jnx2img>batch_convert.cmd "c:\maps-jnx\" "c:\Maps-img\"

Anyway, the problem even occurs if jnx2img script is started more than once from the same command line session.
I'll fix this problem.

Thanks for spotting my stupid error. With the backslashes added, the batch conversion ran okay, but as you noted, the conversions all used the same MapID this time it was 07A304FB .

I look forward to your solution!

Ok, I've updated the jnx2img. New version is available from the same link in the first message of this thread.

And I've also modified batch_convert.cmd script, so it won't require to press a key after each processed file:

Thanks Alex

Problem resolved - this now works perfectly and generates random MapIDs and it all goes seamlessly in the batch conversion too - an excellent solution.

My jnx converted to img have been working perfectly within basecamp, but I have not been able able to get them work on my handheld Garmin Astro 320 or Astro 430 (which i believe are basically the same as the GPSMAP 64. I get a blank spot in the map where my birdseye should be. Any suggestions which settings to try?

Is your GPS unlocked to view birdseye? What directory do you have the .jnx in?

I no longer have an active birdseye subscription on my Astro 320. I have jnx birdseye maps I can view. I have other birdseye maps that I've converted to IMG files with this jnx2img converter. These are in the Garmin directory in the SD card. I can view the map, but it displays as a blank spot on my top map
