The route is very long which makes it very difficult to debug.  I
suggest you add intermediate points in between like this:

http://yournavigation.org/?flat=14.5928&flon=121.0587&wlat=13.878664461713&wlon=121.12744405208&wlat=13.797330599087&wlon=121.06992163242&wlat=13.76264491244&wlon=121.05207153142&tlat=12.596233333333&tlon=121.52638333333&v=motorcar&fast=1&layer=mapnik

Zoom in to waypoint number 2 and you will see some routing errors
along the Apolinario Mabini Roundabout.  This intersection is a little
bit complicated and I dare not touch it as I'm not familiar in the
area.

Testing your route with the OSM-PH Garmin Map (updated yesterday), the
route from STAR Tollway to Mindoro is OK.

Several possible causes of error:

1. Yournavigation routing data is not updated.  Although you can see
the mapnik rendering as updated.  The underlying routing graph used by
Gosmore (the routing engine) is not updated.  Try to contact the main
developer:

2.  Along the way I did found some unconnected highways (particularly
within Batangas City proper).  I fixed a couple but I may have missed
others.
