Question about Garmin Edge 305 GPS Receiver
I cannot get the cadence and speed to register off of the GSC10 sensor. I have taken the obvious step of replacing the battery and the green and red sensor lights do come on when I reset them and they come on when the magnets pass over them but no reading on the Edge from the sensor--I do get speed reading/calculaton from the gps.
Had the same problem. Here is how I fixed it.
1. Changed the battery in the cadence sensor. (GSC10)
2. Turned on my garmin 305 edge outside to acquire satellites (probably not nec but did it anyway)
3. Pressed reset on the GSC10, saw red/green flash (what order?)
4. Here's the missing step: On the Edge unit, go to SYSTEM.
5. Scroll to bottom, choose ACCESSORIES.
6. On acc. page, go to bottom, under Cadence Sensor, to the option RESTART SCAN. Press That. Now your cadence and speed should work.

I had the same problem. I needed to move the GSC10 as close to the crank sensor as possible, then I tilted the GSC10 slightly towards the crank. This is the only way I can get it to track cadence, but it now indeed works. I simply don't use the spoke sensor as my speed is calculated by the GPS function, and my spokes are too wide to be able to use it anyway as far up the spokes as would be necessary.

Hi, I'm not sure whether this will solve your problem, but I had the same issue and it got solved by selecting a different bike profile. I switched to Bike Profile 2 in the settings and now my cadence and speed come up fine. Only when you download your data to your computer you need to set it back to bike profile 1 because otherwise the transfer doesn't work. Go figure. Hope it works. GM

This is for the recumbent problem. I have one also and tried to use two GSC-10 sensors - one for speed and one for cadence. The problem is that the Edge 305 sees two cadence sensors and essentially gorps out. You have two choices:
1. Install the GSC-10 so it picks up the cadence, but does not sense the speed. Let the GPS take care of the speed. This should be OK so long as the Edge can see the sky. If you're in a forested area you're going to have problems.
2. Open up the GSC-10 and solder some longer wires between the GSC-10 and the speed sensor arm. This could be tricky.
I'm going to try the first option and also try to figure out how to open up the GSC-10.
If I can work this I'll post the solution.

Thanks to Aschwerin for posting the solution to the cadence sensor problem. It worked for me. As he/she mentioned, if you move the GSC10 unit closer to the crank arm, your sensor will be too far away from the spoke magnet to register speed data. However, there is a small screw at the base of the sensor arm that you can use move the arm closer or farther from the wheel, in order to get both cadence and speed at the same time. The GPS does calculate speed independently anyway when you're outdoors, but the speed data may be useful when your riding indoors on a trainer.

Go to menu _-settings-scroll down to ant+sport-accessories then switch on cadence sensor may need to re-scan if still no lluck make sure all other wireless equipment is off.
