I recently did a 4 day 1450 mile trip from Albuquerque to Yuma and am not seeing points every 15 minutes. In a couple of instances the times are several hours apart. I pressed OK for a new point when starting out and the next displayed position is 5 hours later as I recall. Any hints on how I can troubleshoot this? This trip was not important but I would like to be sure that I have this resolved before a trip that does need to show my route.
Looking at your trip and the tracking that exists in between ABQ and YUM, it looks like the device had tracking issues toward each end. This typically happens when either the unit is off or, for whatever reason, the device cannot acquire a GPS signal and its current location.
Where do you normally keep your phone? I usually have mine in my tank bag, but it works well in the top case too.
