- Its superseded badge covers 359 files and links to a replacement when the catalog holds one; the site warns newer is not automatically right for a given truck.
Field notes
The table distinguishes NavKal .nav.zenc containers from WinOLS reads and exposes fields such as flash size, rated power, source, read date, and emissions. Its superseded marker applies to 359 files and links to a replacement when one is held; the page cautions that a newer calibration is not necessarily the correct choice for a specific truck. The extract does not show whether the listed files are downloadable.
