Well I have thought about this too - also new Basecamp has a curvy roads preference - but what should mkgmap do about it? You can calculate if a road is curvy or not, but what then? The only thing you can do until mkgmap knows NT format maps which I think has a special "tag" for this, is to increase the road-class. Increasing the road-speed would be against your intentions - as the higher the road-speed - the more garmin algo will punish you for curvy roads... So until we know how Garmin maps tell Basecamp/the GPS Unit to exclude a road from curvyness punishment - the only thing you can do is to increase the road-class... I'm 100% sure the prefer curvy roads switch, works like avoidance - looking for the curvy road indicator inside the map. There is absolutely no change in routing in Basecamp if I set it or not with non NT maps... On 01.07.2014 22:02, Manfred Brenneisen wrote:
Hi all,
Garmin offers "curvy roads" preferences for their zümo 390 and 590 devices.
