I recently spent a week to find out why I have GPS Logging option totally disabled in menu (like grey unselectable entry). Here's the solution for anyone who would have this problem.
Issue: Unable to activate GPS logging
Reason: You were unlucky to purchase on of the "GPS-logging-disabled-region" version of camera, mine was from China Mainland official reseller.
Solution: Change your camera's region code.
Warning: that could lead to warranty void.
Step by step (
pictures here):
1. Format the SD-card;
2. Open Notepad, paste the text «[OPEN_DEBUG_MENU]» (without the quotation marks with brackets) and save it on a memory card under the name 00077980.570 (extension should be .570 instead of .txt);
3. Open the notebook, and save the empty file called «DEVELOP.MOD» on the same SD-card;
4. Insert the card into the SD slot of the first chamber, and closing the slot cover turn the camera on.
5. You will see the developer menu
6. Down arrow to select REGION CODE, and the arrows left and right to switch the code to <01>, and click OK;
7. Pull out the memory card and remove it from the files that we created in the first steps.
You're done. As a bonus, you'll get the full selection of languages, instead of having Chinese/Korean/English.
