my wifes Thai bought from Esri in 2009 Nuvi 1340 was updated to 2012 maps and it worked Ok for a while but now its sending her to the wrong place all the time and 2013 map wont work at all its totally 3D and the old Nuvi cant handle it

anyone got an older non £D map she can load in Thai script ??? I put in my old 2011 Thailand 2D English map and it works fine
