@Ronald-Weaver Not being able to get it to download must be about as good a reason not to get on with BaseCamp as there could possibly be! I can’t imagine what the problem might be as I’ve never met with any such difficulty. I get the impression that it will be scrapped in the not too distant future anyway - to make way for all this interweb and ‘internet of things’ (whatever the hell that is) stuff.
These days, I can’t say I have much difficulty in ensuring that sat navs take me on the roads I want them to. When I first started using them I spent a fair amount of gnashing teeth and tearing hair out I guess. My approach is very much ‘get the settings right’, ‘be consistent’ and use ‘loads of shaping points’ and ‘the K.I.S.S. principle’.
@Drabslab makes a good point regarding standardisation, I think. In my experience, the lack of it can make learning curves in changing between devices and systems much steeper than they might otherwise be.
