I had no luck with the search engine, so I open a new thread to ask your help. I am planning a trip in south America to cross Chile, Argentina, Peru and Bolivia. I have absolutely no experience with GPS but i guess it would be wise to take one with me to avoid getting lost too easily. I need your help to spot a good device to answer the following needs: - navigation from point A to point B on roads - map localization off road (or on back roads that might not be defined in available maps) so I can identify where I am. - possibility to import maps from a computer (the idea is to create my road book on a map on the computer and export it to the GPS), either using Google maps or specific software => I do not know which option is better, your advice is more than welcomed but I want to be able to charge map from almost anywhere (next trips planned in Europe and Asia) - flash memory rather than hard drive for better vibration resistant. Other specifications would be nice but not mandatory: - possibility to connect earplugs to listen instructions in the helmet - built in battery to be able to use the GPS when not connected to the bike Except if it's the only way to get the functionalities I need, I don't need a GPS made specially for bikes (waterproof and so on) as I plan on putting it in my tank bag and using mostly for reference as you use a paper map It was not originally planed on my budget, so I would rather not go for a fency expensive one, just one doing the job ;-) Thank you very much for your help!!!!
