Garmin Edge 1000, Tacx. Use menu and choose “SELECT” -> list of founded trainers…choosen…automaticly backed to main screen. And now…what now? When I will know that is connected ? And what really means “POWERMATCH ON/OFF” ?
If you tap the screen and select STATUS PAGE, swipe left/right to see the sensors page which will indicate if the trainer is connected.
Powermatch is a feature that uses the power coming from a power meter rather than the power from your trainer to for trainer control. This ensures that if our interval is 300W, for example, that the power will be 300W from the power meter and not from the trainer.
