Question about Garmin Edge 305 GPS Receiver

1 Answer

Distance and average speed don't compute.

My 305 gives me cadence and speed and heart rate, but will not give me % grade, distance traveled and average speed. It has spent the winter in the basement, but once re-charged, it only gives incomplete information. I'm confused why it gives some info, but not other. Any suggestions?

My solution included changing the battery in the cadence sensor (GSC10). You might not need to.
1. After changing battery, take bike outside. Turn on Edge 305 to acquire satellites (might not be necessary..)
2. Press reset button on GSC10. Should see red/green flash.
3. On Edge 305, go to SYSTEM.
4. Scroll down to ACCESSORIES.
5. On Accessory page, scroll to bottom, under Cadence Sensor, and press RESTART SCAN.
That fixed my Edge 305 - cadence and speed do appear now.

A Five cylinder low speed engine has a bore of 29 1/2 inches, a stroke of 63 inches, and a rated speed of 123 rpm what is the average piston speed.


There are two ways to solve this homework problem. If you want full credit, you will solve it using integral calculus as your teacher most likely expects. I am WAY too many years out of engineering school to remember how to do that.
The simple solution takes advantage of the fact that speed is scalar that is presented in units of distance over time, so all you need to know is the total distance traveled over a fixed interval of time.
The stroke is 63 inches and the engine makes 123 complete revolutions in a minute.
123 x 2 x 63 = 15,498 inches per minute average piston speed or 1,291.5 ft/minute
or 14.676 miles per hour
This must be a steam engine.
If your teacher is picky about significant digits, don't forget that the original problem had only two significant digits so the answer you give should have only two significant digits.

Unit is measuring cadence and heart rate, but is not measuring speed, distance or ride time.


Check to make sure your speed/ distance sensor is in alignment with your wheel magnet. If it is then check the battery in the sensor.

Speed and distance are on a different sensor than the cadence.

I have no speed or trip distance showing, cadence is normally ok. also my watch strap has broken and because it is glued on i cant get it fixed!


Since your Cadence is working then there is a problem with the actual speed/ distance sensor. First make sure that in your settings you have speed turned on. If so then...
1) Your battery may be dead = Replace CS sensor
2) The distance of the sensor and magnet is not set correctly = make sure magnet on spokes and sensor are within 1-2mm of each other.

Polar can fix the strap, you need to send into an authorized service center. They replace the entire strap unit. If you send into Polar to get the strap fixed, then you can send in the sensor unit as well for diagnosis if you want. But if #2 doesn't fix, then it's #1 and they will just tell you to buy a new one anyway.

The speed (and worst of all distance) was droppping out now and then also the heart rate would hit 200 when rolling down hill. I think I have fixed this problem by leaving the phone at home. I've ridden...


2 Seperate issues:

Heart Rate - The CS200cad uses a coded transmission for the HR, When you have a HR that spikes that high, it is because for some reason the signal has not coded correctly. Here are a number of ways to help with that issue.
1. Make sure you have good contact between your chest strap and your skin.
2. Make sure the Heart rate sensors on the strap are wet. Or use a conductive cream to improve contact.
3. Make sure the strap is on correctly. Up high on the chest just under breasts, Polar symbol centered on chest and upright. Strap tight enough to keep from slipping
4. If the strap is older, make sure it is clean. Salt can build up in the strap.
5. If the strap is over 2 years old consider replacing.
6. Check Battery

For the Speed/ Distance - Same sensor (front) make sure that the magnet on the wheel is within 1-2mm of the Fork sensor. The magnet should align in the middle of the sensor, with the sensor just slightly angled into the magnet. When the magnet and sensor have a good signal a small red light will flash and you may hear a click when the wheel is rotated. If none of this works you have a low battery and will need to replace that front sensor.

Can not get speed and distance to register although cadence does register


Looks as if your GPS is turned off (GPS transceiver). Or the cadence is OK but the device on the wheel to capture rotation is not well installed.

See GPS device via
Settings>System>General>GPS and check that GPS is ON

When I training indoor my edge 305 doesn't show me speed and distance even if the cadence sensor works properly


Try start your training device outdoor for a check. If then it is working, the issue is about the device needs to see sattelites to perform measurements and register speed.

You may try switch GPS device off, which is said to be an indoor mode for training.

My Garmin 305 wont record calories when I'm in the Gym. I select the "Other" sport mode, the little guy skiing, and It doesn't recored or even register calories? It records during my Jog sessions while...


The 305 uses distance to calculate calories. They sell a "foot pod" that you can use indoors, and that will count your calories by calculating the distance you have traveled. The problem however, is that using distance to calculate calories is so inaccurate! The calorie count that the 305 provides is almost always WAY too high. Other heart rate monitors use heart rate to calculate calories burned, and it is a much more accurate measure. My garmin thinks i burned 700 calories an hour today while i was snowboarding, and, while that would be nice, there is NO way it's true!!
