I could call Veracity or AIM, but also this group may know off the top of their collective heads.
I use my EVO 4 as a dashboard and rarely download the data, like not for several seasons, but I wanted the data from my last session this time. According to the manual it records to a circular buffer, deleting oldest data as new data comes in, but when I look in the data logger download all the data is old. Any explanation?
Also, given that the GPS knows the time to a nanosecond, why does the time in the logger drift? My Garmin and TomTom never need their time set.
