And if using a secondary speed sensor does that provide more accurate mileage also? Secondly, If I decide to go with a secondary speed sensor, I would like to use the Duo Trap S since it is a nice clean look. Will the Duo Trap S be compatible with the Edge 500? Thirdly, can I use either MapMyRide or Strava (or both) with the Edge? And my last question is what is the best out front mount for the Edge 500? Thank you, gjmen
1. The speed / cadence sensor will provide speed info that is more accurate than the GPS data. If no sensor is detected, it does fall back to GPS info.
2. I believe that if you have the sensor, ir automatically calculated the meters of development using the GPS + sensor information for calibration.
3. If it is ant+ compatible, most probably.
4. Yes, you can upload files directly from the garmin device to the strava website, or use garmin connect in conjunction with strava.
5. That is probably a personal choice, but many like the SRAM quick mount, it's cheaper than the garmin branded mount.
