Making a short trip to Mexico next week, and likely a month long venture in May. I have a SPOT GPS tracker and am wondering about the best use of the "help" (NOT SOS) and "custom" buttons. Typically my "help" button is set up to say something like "Aw, Crap, will you call AAA for me?" But since AAA probably won't cross the border on my behalf, I should use it for something else. Any message you wished you could have sent or were glad you could? I have the ability to send two pre-composed messages above and beyond straight up "SOS!" Thanks for your ideas!
