I'm finding that some of the new highways around here are throwing my Nav a curve, so I'm thinking about buying an SD card update. However, I know there must be a "lag" between the update and the actual roads. Does anyone know what that delay is (months/years)? Do they issue a new update every month? For example, is an April 2016 map update different/more current than a March 2016 update? I'm trying to figure out long it might take for a "new" highway to show up in a Nav update.
