OK, FF, thanks for that. I’m on another steep learning curve here. I hadn’t realised Paul had updated his guide. I’ve looked at both GMAP2GPX and Cuesheets.
GMAP2GPX - the link displays a website for ‘elsewhere.org’ which has a big ‘Download’ button which tricks you into downloading something called ‘FileOpenerSetUp.exe’ which I mistakenly thought was part of the application installation process. Only when I had narrowly avoided installing several junk apps, including some Norton crap did I realise I was being sucked in. Having to allow it through my AVG should have alerted me!
I click-and-dragged the ‘GMAP2GPX Bookmarklet’ to my Chrome Bookmark bar but this has absolutely no effect when in GMaps.
Drilling down on the ‘‘elsewhere.org’ website I find a list of educated sounding comments which indicate that this app is broken and has been for some time.
Having abandoned GMAP2GPX I turned to CueSheets. I dragged the bookmarklet onto the Bookmarks bar and this time, when in GMaps, a result was displayed. It’s pretty geeky-looking (at least to me!) but there are options to generate ‘GPX Output’ and ‘Garmin Output’
I tried using the ‘Garmin Output’ but it insists on my having ‘Garmin Communicator Plug-In’ installed and won’t go any further, despite the fact that the relevant Garmin webpage insists I already had the most up-to-date version installed. So this route is blocked for me.
Using the ‘Generate Gpx Output’ option gives me a nice page of .gpx file text which then had to be converted into a .gpx file. Casting about t’web, I found ‘GPSVisualiser’ which I’d read about previously but hadn’t hitherto needed. This did indeed generate a downloadable .gpx file which displayed nicely in Memory Map as a plain Track, from where I could export it into Basecamp.
When it came to Basecamp however, the .gpx file from GPSVisualiser imported as a series of waymarks and not as a Route nor as a Track.
As more knowledgeable readers will discern I am still somewhat ‘digitally challenged’ when it comes to all this GPS stuff, despite having used one satisfactorily for a number of years. But for me, DIY by GPS route creation has just become a lot more of a faff unless further homework can improve my basic skills!
EDIT: posted the above before refreshing the thread, so will now go away and follow up AndyC's directions!
