I got this to work on the weekend while away camping. I was board waiting for something or other and thought I'd give it a go. My GPS's batteries were flat so had to do something caching
From my smartphone I went onto GC and made a PQ.
Seconds later when that was ready, I went via the email to my list of downloadable PQs, on GC.
Download the new PQ.
It went somewhere onto my phone, and was then stored there.
It then shows you the zipped file.
Back to C:GEO
Go to the "Stored" file on the main menu screen.
Hit the Menu button and hit "Download GPX".
Touch that and it starts downloading to c:geo
It took about 10 or more minutes to download the 900 odd caches, but they were all then visible on the old google satellite "live map" screen.
Like before the proverbial hit the fan and google stopped their free map bizo.
From the time I started playing around with it (ignoring download time) to the time I was able to view the 950 caches within 100miles, was only a couple of minutes or so.
That is approximatley the way I did it.
It is fairly simple, there aren't many other options to take. I'm not really fluent in GPX and the in depth technology of it all, but was
very surprised at how easy I got it to work. It's not mapsforge, but is straightforward.
Not sure if this answers that question exactly but it may help other c:geo users, and it allowed me to use c:geo like I used to(before I got my GPS), by searching via the google satellite view.
cheers
