Wonder if anyone else have this problem. Noticed for version 100104 and current version 100111, while routing, the bolded coloured route will sometimes disappear during certain section of the route though the route will still be active.
I'm experiencing this from mapsource generated sg portion then combined with road poi and sla using gmaptool. Have no opportunity to test other combo yet.
No one else have the problem I mentioned? I realise when it happens, zooming in may show the coloured route, zooming out will revert to the same problem. It seems only at certain route, with auto-zoom enabled, the problem will surface at certain zoom level (when it auto-zoom out) cos I've tested manually zooming in/out many levels when the coloured route is showing w/o losing the coloured route.
Let me guess probably you have a Nuvi 765 GPS.
That's the price you have to pay to have this very smooth display most of the time.
This lag occurs always at the same places on the map.
The 765 doesn't like very detailed maps and anyway doesn't display POI when routing to have a smooth display. In map details choose normal or less level.
The lag occurs also whith official Garmin maps (ie. City Navigator Europe)
