So, I am in South America with no laptop, just an Android tablet, Android phone with handlebar mount and finally with working power, and a Garmin nuvi 2455 and a 285W. I got Chile maps to work on the 285. Argentina options fail to be recognized on either. South America CN2013 fail as well. Using Sygic app on the phone right now, and it is mildly functional, but not great. And, none of the gas stations I have found have paper maps. How can countries that demand paper cash for everything have so few ATMs and so few places selling paper maps? Blown mental gasket. I guess this rant post should go into the nuvi thread. Too lazy to find it. What would you do without map source? Edit: never mind, I borrowed a laptop and ...obtained... City Navigator SA 2013. Bought a 4GB SD card for the 2455 and loaded all SA maps but Brazil. 4Gb is $15 down here, when 32GB cards are now around $13 in the US.
