As an Garmin user for years who´s looking for an non properitary alternative, I found Kurviger.
While generating first own routes I try to use different routing profiles for different sections of one route in a way fastes route from WP 1 to WP 2 (to reach the interesting area fast by using highways e.g.) and from WP 2 to WP 3, 4, 5 etc. using curvy route profile to have fun and from WP 5 back to WP1 (6) again using fast route profile to go home.
Till now I can´t find this feature.
Any hints or ideas?
Thanks in advance
