Following on from discussion in other recent threads, but starting a new thread to avoid taking any of them even further off-topic...
I was thinking about Garmin's 250 point limit on GPX Routes, and the effect that has on navigability when your GPS device doesn't support maps or autorouting or give proper turn by turn instructions natively. Since my 200km audax has considerably fewer than 250 instructions, it strikes me that it should be perfectly possible to create a useable GPX Route from the routesheet, by plotting routepoints only where turn instructions are actually needed.
What I would then like to do is add the instructions from my routesheet as custom text. And maybe suitable symbols (eg turn arrows).
So, what's the best/easiest way to do this? Is it something I could do in Basecamp? (I've never really got to grips with Basecamp but am willing to try.)
I know RWGPS lets you create "custom cues" if you have a paid-for account, but they can only be exported in the form of TCX Course files - I want something more universal, if possible, so I'm assuming that GPX Routes would be more suitable.
