Im traveling back and forth between eastern Canada and western US. In both locations when I first get there I dont get a speed reading on my Edge 830. Its blank and it takes about 10-15 minutes before it shows. Further the ride doesnt begin until the location where it starts. This happens every time in both locations. There is no delay if I do a second ride in the same location. But the first ride always seems to incur a delay. What can be done about this problem?
