I want to know how to edit the track coz i found out that the roundabout pointed (sorry i have to use google map) is not connected.
I updated the latest map and when i try, the route is not able to:
1. u turn when i reach the roundabout;
2. moving from bintulu to miri using this road (always asked to u turn when possible)
The problem has already been fixed in the latest cgpsmapper release: viewtopic.php?f=46&t=8442
If you're using the MFM-Garmin NT map, you'll just have to wait for the 2013.20 release.
(You never said which map and device you're using; I'm assuming you're a Garmin nuvi user).
