I have installed thru MapInstall some osm+vfp maps without any kind of problems either on my oregon or on a sd card. The last osm+vfp from alternativaslibres.es I could not, for exemple it warns me that my 16g or 4go sd card has not enough memory for a 230mo map, wherever on oregon or in the slot.
I upgraded to the new beta basecamp, same warning. My cards are new. there is a trick but i don't find out it
any idea ? Thanks 4 the help
