[2019-07-01 - Brand new Zumo 595lm] \nNewbe here and hopefully just ignorant. Can anyone tell me why, after I add a stop exactly along an existing route (with only a start and end point), when the device recalculates the route it changes it?\n\nThis is blowing my mind. I hope there is a logical explanation but, as of now, it seems like a serious defect in the calculation logic. Why would adding a stop along a given route, change the route downstream from the stop?\n\nI noticed this when adding this point to a 10.75 hour ride and it added 30 minutes to the ride! I figured out that it was taking me on a different route between the newly added point and the destination.\n\nYes, I have triple checked (with an additional pair of eyes) that the new point is precisely along the existing route.
