2012 MS 47,000miles. Took our usual Trip from NY to Philadelphia with navigation set to the supercharger just off the Penn Turnpike. Once Charged we always reset the navigation to our destination in Philly. This time when we entered the new destination the map zoomed as expected but it just continued to calculate, then "still Calculating" but never completing the route. After canceling the route, the Map would show our location on the road until the location icon (Arrowhead) disappeared off the top of the map. I could manually pull the map down and see the icon again. We rebooted the MCU on arrival. On the return trip the next day same thing, no problem Navigating to the first destination (Supercharger) but unable to calculate the second leg of the trip. The next day after arriving home (no reboot) was able to Navigate to first location but again not the second. Any ideas? Is this possibly a sign of MCU issue?
