Re: [Gpsbabel-misc] need help with converting to GPX and keeping timestamps

[tsteven4 <tst...@gm...>]

Tom,

Can you send me an unedited .nav file with pauses, i.e. the mainnav 
software reported total time and moving time are different?  Perhaps I 
can see some change at the pause.

I also need a unedited .nav file to build a test case.  We need this to 
make the mainnav style available in the gui as an internal style.  This 
.nav file will become part of the project and available to anyone who 
looks through the source code.  This file should demonstrate the pause 
as well, it could be the same as the first.

Thanks,
Steve
