I have the 1030, with latest firmware, I also have the new speed sensor in the hub of the wheel and Vector 3. Which speed is supposed to be recorded? From sensor of from GPS? Looking at my .fit for todays ride makes me wonder. I'm passing over a motorway, speed is above 30km/h power output is high since it's on a small gradient. All of a sudden speed drops from 30+ to 18? What, why? Wheel is spinning I'm not braking, power output is normal, when I'm over the motorway, the speed is again recorded normally, has risen to above 35km/h+. Why is this happening? It's not just this ride, it's at this place for every ride.
Which is of these to possible problem am I facing Garmin?
Senor is not used, what is the point of the senor then?
GPS is used, and goes bananas when there is air under the bike?
The speed sensor takes priority over GPS data for speed. Check that the wheel size is correct under the sensor details. The magnet less Garmin speed sensor uses rotation through the earth's magnet field to determine a wheel revolution. It could be that you are passing by some local magnetic field that is interfering with the sensor.
That makes sense, so traffic light sensors would cause them to go haywire and perhaps the bridge has some magnetic pick ups for traffic measurement, or perhaps it could be the steel reinforcement in the concrete?

So the old senor is much preferred then. I guess other magnetic situations will cause similar problems then.
what? Well I'm not doing a wheelie and breaking front wheel while outputting 600w.
The new sensor type is better fitted to the front wheel, on the back the signal can get lost as the wheel rotates. This gives a bad signal to the Garmin which will give you a slower speed reading.
I have not seen any range issues with the sensor on the rear hub. I have seen issue being caused by part of the chain being magnetized. This can be is fixed by de-magnetizing the chain or avoided by moving the sensor to the front hub.
