The most accurate source would be from a known elevation point, like a benchmark. It's just trying to find the actual elevation of that BM that might be tricky. I have mine set to use the GPS elevation, it's plenty accurate for me.

It reads in real time when on the screen as a data field, while driving up and down hills. You'll know what I mean when you try it once.

I don't really use it so it's not a really big deal. Would just be nice to have all the features work when you pay that much. I am sure it is a glitch and Magellan will eventually figure it out in a firmware update in the future. Like I said previously everything else works great. I get my elevation readings from the map or unit itself. Is it that picky on what you put I for it to function properly?

First, the 610 and 710 are the same except for the driving direction maps & a bit more memory on the 710.

The graph will show pressure changes over time.

The altimeter can be set by you to read from the GPS, the map or the barometer.
What I have found is that the barometer works but is not as accurate as the GPS for altitude readings.
So, to calibrate the barometer you have to input an accurate elevation or pressure. Where are you getting the elevation/pressure readings?

The bottom line is that these units are pretty good GPS receivers, but if you really need an accurate barometer you might be better off just getting a good barometer.
With battery life being what it is, it seems to me to not be worth running the barometer.

The barometer is a cool sensor to have but I never depend on it for anything.
After all, I bought this thing because it is a GPS receiver! 😛

My 610 Canada has no problem changing settings on the barometer, and it does work. I keep mine turned off and don't use it though, but when I use it once in a while, it works fine.

Since I can calibrate my 610 barometer, I made various changes to the barometers settings in an attempt to induce behaviour that would duplicate the problems you guys are having. Changing the settings as "soleful2001" mentioned (Map, GPS and Barometer) produced no change. I was still able to recalibrate by entering a different value into the elevation field. However, changing the units of measure in the sea level pressure field (e.g., from inHg to KPa) did not show up until I completely exited to the map screen and then returned to the barometer screen.

Guys, I'm going to contact Eric (Product Manager) on Monday and I will bring up this problem and see what he can tell me. Since the original release of these units the firmware has been changed several times, so maybe - just maybe the calibration procedures have changed... Let me ask...

Stephen,

I don't plan on exchanging mine because it is not critical to me.

If a fix is possible, I am unaware of one. I have tried calibrating with all three barometer settings: Map, GPS and Barometer. Not successful saving in any mode.

If it is important to you I suggest you exchange it, and make sure that Magellan checks the replacement and ensures it is functioning properly.

I have a 610 and am unable to get the barometer to work. I am calibrating it according to instructions. I am not sure if my unit is defective (all else works) or the is something else I need to to. Any suggestions besides exchanging?

Make that another 610 owner unable to calibrate the barometer.

Thanks for the info. I know at least one other person with the same issue.

soleful2001,
I do have the same unit as you (610) and am able to change the setting and it is accepted.

Yes I have a 710 but the 610 is the same except for the driving map.
It should behave exactly the same as a 710.

In 1997 I dislocated my left elbow, breaking the end of the ulna bone and damaging the bursa sac.
So ever since then I use the bursitis in my left elbow for pressure change warning.

It's become a very dependable, if not precise, barometer.
But I would recommend a good barometer for a less painful warning! :blink:

That is interesting, you have the 710 correct? This may be unique to the 610 units then.

The only thing I use the barometer for is watching for changes in pressure when I am out on the trail. This gives me a little more advanced warning if a big change in the weather is about to occur.

Thanks for the info Phil

I usually don't use the barometer but I just tried it.
I entered my current altitude and got my current pressure.
Then I entered a lower pressure and it changed to what I entered and showed a higher elevation in feet.

The few times I have used the barometer it has always calibrated for me with no problems.

My house is 38 feet above sea level by the way.

I noticed this the other day when I tried calibrating the barometer. I followed the manual's instructions, but when I entered the new value, selected "ok", it would not change to the new value.

I know of at least one other person who has experienced this.

Anyone else?
