Thank you so much for educating me about this feature of this GPS device. Another question for you, please: Where do I place the Points of Interest file..... the .gpi file??? Thanks so much.
Wait! I kinda sorta figured that out. Where I am the most confused is how to use the SD card as the place to keep my map. Do I simply establish a MAP file on the micro SD and place the two files in it.....the .gpi file and the GMAPSUPP.IMG in there?
To further muck up the board (I do apologize)...I had acquired the NavSat map which was clearly labled Costa Rica 6.0. This map is called Cr_2012_05_02_navegacion. Is that because the first map I discovered was an English map to begin with? Thank you for helping me learn ..... particularly use of that SD card (I am advised that although you can STORE a couple of maps on the SD, you can only USE one at a time. Can't figure out how to do that! Thank you so much.
