Varia Vision in-sight display enhances your road awareness by putting the information you want right where you want it -directly in your line of sight. The featherweight device attaches to your sunglasses, and it displays key data from your compatible Edge device such as performance data, turn-by-turn directions (if available), text/call alerts and more. Pair it with your Varia rearview radar system to warn of traffic approaching from behind. With 8 hours of battery life and a touch panel to cycle between data displays, it's easier than ever to keep focus when trying to nail your targets for a workout, find the next turn or stay clear of traffic.
