yea... won't work with geotags.com service, no kml output there. A bit larger patch is required to fix this issue

It seems to me that google.c is using KML and for example yandex.c (though broken as far as I can see) is using GPX for the routing.

Just a quick read but
looks like it

In theory using yandex.c with the google or geotags.com URL should parse the GPX route into something reasonable, if yandex was working before
