Hello All. As the title states, I need help in learning how to plan routes and transfer them to GPS or other devices when I travel through Central and South America. I looked on some threads here but a couple started so long ago and I do not know what is accurate and currently available now, as technology changes so much! I will be traveling from Illinois into Mexico, then heading all the way south to Argentina. Regarding electronic devices, I currently use an Iphone for navigation (in my car) and I will also be taking an ipad. I don't have any gps devices for my motorcycle but am willing to purchase if needed. If there are (very current) specific forums and threads here that you believe will help me, will you please post a link to the thread? What was the BEST thing you did for planning routes and loading them onto a device while going through Central and South America? What do you wish you knew or did before going on your South American journey (related to navigation)? I want to learn from you if you did a Central to South America trip! You have so much knowledge I can benefit from. Sort of tangentially related, I have heard that TMobile works pretty well in Central/South America and it's easier than buying multiple SIM cards. What recommendations do you have for mobile devices, and service providers? How frequently were you without service and what did you do during those times? And finally, what did you need to keep all your devices charged? How many USB ports are enough/too many/not enough? I appreciate links that will help me understand what problems I will face with navigation, what products will help me reach my destinations each day, how to download and transfer routes, and any youtube videos, links to products and services or other links to help me find my way to Ushuaia. Thank you.
