Arrival Time Flipping on 680 After Update to 4.2 Firmware


I recently upgrade my Nuvi 680 with the new firware version 4.2. Now I occassionaly observe that the arrival time estimate is flipping every few seconds between what I believe is the correct calculation and another value that is off by a number of minutes from the correct value. I have seen it flipping between two values that are 20 minutes apart and flip values every 5-10 seconds. I have MSN Direct active, so I do not know if it has anything to do with that. I just know that I have only observed this after the upgrade to 4.2. I have also seen this flipping between other values, like 5-6 minutes.

Any one else seen this? Any thoughts on perhaps "fixing" this problem.
