Currently with mkgmap created maps (just like most other maps) Mapsource tries 3x to find a route when using the autorouting tool. I have noticed that using Netherlands Onroute Fietskaart Mapsource tries much harder to find a route - sometimes it restarts 15 times until it has found a route. It would be great if we could have the same behaviour.
I don't know at all where a parameter for rerouting tries is placed inside the maps, but just if someone finds something, this would be interesting to improve routing (on each successive try, Mapsource lowers a bit its rigorosity of the route quality, but better a route than no route). Actually I think there is no parameter here. I have fiddled a bit with my styles and now I also get maps that try sometimes 15 times to recalculate until a route is found. I now more or less get routes with up to 140 direction changes without problems. I even had some routes were Mapsource put 229 direction changes without a via-point - it needed about 2 minutes to calculate however. The patch I supplied for Mapsource should do the same.
