I use mozilla myself and use 'save link target as html'. But yeah, the python parser isn't that pretty and easily gives up when the input doesn't really match the couple of routes I tried. There are 2 html options, for one of them mozilla also grabs the images and rewrites the html output, my guess is that the rewrite breaks the parsing.
In a way the mapsonus routes should be a temporary solution as I want to get on-line routing in gpsapp at some point.
btw. fixed the Trimble TSIP protocol, turned out to be that the ARM uses a slightly different layout for double precision floating point numbers. v0.8 has just that one little change.
