I have been having weird elevation graphs from my garmin edge 1040, the elevation graph is all over the place and not reflecting the reality of the terrain or elevation.
I do not know if this may be a firmware issue but at the moment is pretty much not usable
i do not understand why the edge is so off? i have updated, it has the latest firmware. updated maps everything…
is my unit dead.
i can still use climbpro during the ride it show the climbs and everything but the graph elevation and total elevation of the ride are completely wrong.
I had the same problem with my 540. I followed all the troubleshooting steps but it never fixed the issue. The first time I noticed the problem was right before the warranty expired and I managed to get it replaced under warranty.
I’m not sure why it went but I had the same thing happen on a Garmin 500 many years ago. That one was well out of warranty.
The only way I can think to prevent it, is to thoroughly wash it more often to keep contaminants from getting into the barometer holes.
Just call Garmin and they will sort it. The barometer in my 830 failed (data was obviously wrong on graphs in Garmin Connect). Even though it was way out of warranty they sold me a refurbished one for $100. I was very happy with this resolution.
I’m Germany and the barometer in my 530 failed, too. Seems to be a pretty common issue. Mine was still under warranty and I contacted Garmin through their website. They exchanged it with a refurbished one. Not too thrilled about this, I do not get the same battery life out of it. Not sure if this is an issue or just a setting somewhere. Unfortunately it seems to happen randomly. However, the entire process took only a few days.
I contacted garmin and after a month of ping pong emails they agreed to change the unit for a newly overhauled device… not sure what it means.
i shipped it yesterday by UPS and i hope to get it back within a week. my country has not garmin and the supporing garmin countries did not manage to make a shipment label to where I live.
I am not that sure about that overhauled device… i bought the garmin in june last year and i have 2 years warranty now i do not know what kind of guarantee i will get with this overhauled device? will it run only for 90 days or until the original 2 year warranty expire?
I’ve always found it odd that they use a barometric sensor to tell the terrain change. Being based on essentially atmospheric pressure (which can change during a ride), it seems fraught with a large possible error potential. Given that the unit uses GPS, and ‘altitude’ is possible from GPS, why use a sensor that isn’t measuring the actual terrain change? They use the GPS signals to measure speed, right?
I always thought that the ‘correct terrain’ button in Connect was a self own for how inaccurate their Edge devices are (why not use published topographical data by default?). After spending so much on them. Also the opening for the barometer is so small, and could be partially or fully blocked by something as simple as sweat, rain, sand particles, etc, and depending how sensitive the sensor is, it can be affected by any pressure irregularity. But yeah, the GPS signal can be blocked by trees and buildings, but how do they measure speed in those instances, a hall effect sensor?
That correction button has had rather large corrections on some rides, making the built-in sensor rather worthless IMO, and Garmin’s connect system is the only one that has the ‘real’ terrain based on topographical data. .
