Hi there,
On one of my routes my 840 started crashing at exactly the same location everytime I ride that route.
It seems to happen when it completes a climb and then restarts a climb.
Is this a known issue?
I'm on the latest update.
Based on the issue you are experiencing we recommend connecting your device to the USB port at your computer, and synching with Garmin Express to update your devices GPS data.
That might (or might not) stop that particular crash but it still doesn't fix the underlying bug. The Edge mapping engine shouldn't crash whatever the GPS data and testing for this by deliberately feeding it garbage should be a key test in quality control (and cyber security).
