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.
