Can I use the camera to delete the GPS log data?

To delete the GPS log data with the camera it is necessary to format the memory card  in the camera.
WARNING: There is a risk of data loss. Formatting the memory card will erase all stored data.

If you wish to delete the GPS log data without formatting the memory card, it is possible to delete the log files by using a computer. Access the folder \PRIVATE\SONY\GPS of the memory card and delete the log files.
