Our Fusion Hybrid is a 2016 model (just turned 1 year old) and has the SYNC2 system. I see that the SD Card for the NAV system maps is at level A5. I know that A6 & A7 are out and that A8 is either out or due out very soon. Does anyone know of anywhere that posts what areas of the country changed in the maps for any given release of maps? The $150 charge by a Ford dealer to put a new SD card in the center console is a little short of ridiculous when it seems that Ebay has them for $50. Thanks, K
