Don't know if this is the correct place to ask this, but here goes:

Does anyone know the file format of the Streets & Trips route files?
I've looked at them with a hex editor and can find nothing I can
recognize as a lat/long coordinate. Plus, the waypoint lists start at
different places in the files! If I could recognize what is going on in
the variable header, that might help too.

My goal is to write a program that can read the S&T file and convert the
routes into something the gps can use.

Thanks,
David M.

Don't know if this will help you but the folks at GPSBabel (open source)
have had a go at this. Babel can read route points and a companion
utility ST2GPX can read/write pushpins and route points.

Thanks VERY much, Mike! I tried to use GPSBabel in the past but did not
know the source was available.
