Thread: GIR_Editor

@turboccc
Have you ever played around with jcv files.
I'm thinking that if we could extract the images, edit the images and then put back custom Image.
This could be fun.
I tried with hexeditor but don't know enough about garmin format to find the image blocks.

Hi dasilvarsa,

Sorry for not responding on the other forum. I looked twice at the JCV file, but I could not find how the data is stored. I do not know if they store the JCV pictures or the GPS makes them on the fly based on location information. For sure, I do not see any image format I know or that I have seen in other files. One more mystery on my plate... The best would be to disassemble the JCV firmware and find out how the files are encoded. This is a huge task.
