Basecamp alternatives (more or less)
People complain that Basecamp is hard to use but these alternatives might be harder.

* QuoVadis -> Can read old-format Garmin maps (not NT). Can do routing. (paid).
Online routers
* Rwgps/Garmin Connect and others.
* Gmap4 -> Online mapping/routing. (Like Rwgps or Garmin connect). It appears to have some additional map options.
Other sorts of programs (not basecamp alternatives).

* GpsPrune -> Basic GPX file editor.
