Missing GPSBabel

You encounter an error message such as "%%os%% Can't Open TWL Files" when trying to open your TWL. Customarily, this means that GPSBabel is not installed on %%os%%. The OS won't know what to do with your TWL file, so double-clicking to load the file doesn't work.

Tip: When you have another program installed that you know will open your TWL, you can select it from the other programs listed (see "Show Apps").

GPSBabel is Out-of-Date

It is possible that your version of GPSBabel isn't able to open your Naviguide Binary GPS Track Data File file due to incompatibility.

Tip: Right-clicking on your TWL, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
