I totally agree. They are useless. I rode the vector 2 for a few years and they had minor issues when they were released but nothing as bad as this. I still have not heard back from Garmin. Bad company.
What do you mean you haven't heard back from Garmin? The second response in this forum is asking you to send your file to someone at Garmin so they can assess what might be wrong. Something seems a bit amiss about this.
