hello
I am a developer who previously developed a navigation add-on under the name Heewon Black Box.
This time, we have re-released an app with the same function as Heewon Black Box under the name Navi Black Box.
Supports Kakao Navi, Mappy, T Map, and Naver navigation.

How to use
1. Turn on Navigation Black Box and click Run.
2. When you run one of Kakao Navi, Mappy, T Map, or Naver Navigation and the navigation guidance starts, the video and audio are automatically saved.

1. Videos are stored in internal storage and can only be viewed in the app. Previous videos may be deleted depending on memory conditions.
If you want to save it to the gallery and keep it as a record, select the video you want in the app and press the save button to view it in the gallery.
2. It is possible to split the file and save it, but recording is not possible for about 1.5 to 2 seconds between files.
This is an error that occurs when you record and save a video again and then record it again. Please refer to the settings.
If your device has ample storage space, we recommend continuing to use storage.

If you have any inconveniences or improvements during use, please leave a comment.
thank you
