- Vision doesn't pair effectively with the 820. It shows the prompt to hold close to the 820, then shows a prompt that says it's connected and asks me to "Acknowledge," without any clue of how to do this (on the 820? On the Vision? HOW???)
- Even when the 820 shows that it's connected with the Vision in the Sensor list, the Vision continues to display zeros for data, and incorrect time and temperature readings (91F, 3:59PM, even though the 820 shows 11:03AM.
- Changes to the "Display Settings" section of the 820 Sensors UI for the Vision have no effect.
- After a few seconds, the Vision unit disconnects, and then cycles through the connection and Acknowledge loop again, with exactly the same zero data displays.
- I'd love to try updating the Vision firmware (the 820 is running the latest firmware), but the Garmin Express utility on my Mac fails to detect the Vision unit, so this is impossible.
Looking forward to your support, so that I can use this product vs. returning it.
