What best settings to use in the 530 for routes where there are places it's going across the road (because you can lift the bike over embankments, traffic islands etc.). Just because i can manually draw the route in RWGPS doesn't mean the 530 will faithfully follow it i've learnt. Otherwise how should i plan my routing in RWGPS over areas like that when i know the 530 will have a mind of it's own (it has to follow the rule of the land) and direct me off my magenta route.
