Did you ever manage to set up SPOT Adventures Dave..? Trying to set it up so waypoints are saved. The mobile app seems to save the messages indefinitely, but I thought I'd give the adventure set up a go... last year I left it more than a week and it was all gone... but earlier this year, idly checking the mobile app, I was pleasantly surprised to see it all still there.
