Vector will deliver both combined (standard) power wattage numbers to any ANT+ power meter, for example a non Garmin unit, or older Garmin units that support power – like the FR310XT. However, for the Garmin Edge lineup they'll also deliver Left/Right power. In fact, the Garmin Edge 800 will also be getting an update to bring it other power meter data fields it previously didn't have. The Edge 800 will be receiving a firmware update that enables a new interval mode, which allows you to track power across a series of intervals.
