I updated the map in my 14 with the 2017 map. Only you can really decide if it is worthwhile, but for me, at least, roads that are new or have been reconfigured now don’t throw the system into a “route recalculation” tizzy when it thinks you are driving off into the middle of nowhere. It takes a long time to apply the update, close to an hour. During that time, 1) the radio has to be powered on of course and 2) you can’t listen anything.
