Software update - 310xt now works for OWS!?! (Page 3)

Yeah, the line won't change any - that's a known.

First data set from this morning on an openwater swim race here in the DC area. Today was a 'training run' day, tomorrow is the actual race.

1-Mile Swim (measured by race officials twice as 1.0 Miles by GPS):

FR305 in Swim Cap (Baseline): Measured as .98 Miles
http://connect.garmin.com/activity/34972859

FR310XT on right wrist with new firmware: 1.12 Miles
http://connect.garmin.com/activity/34970750

FR310XT on left wrist with old firmware: 2.47 Miles
http://connect.garmin.com/activity/34970949

Obviously, as expected the maps themselves on the 310XT with or without the firmware are dorked up - but the data using the new swim mode is MUCH closer to the baseline swim-cap (and actual distance). The swim cap had it at .98 miles (for 1.0 mile course), or within the margin of error for GPS. The new firmware pegged it at 1.12 miles, a touch bit long, but much better than the 2.47 miles the old firmware put it at.

More details later...

Anyone else having trouble upgrading software from 2.6 to 2.9? My ant agent works to upload workout data to garmin connect, but wont send the software to my device. It has the correct device listed when I download the software but wont transfer despite my resetting and sending data repeatedly. Frustrating...I really want to see my swims.

I had the same issue. The fix was to add the Garmin download site to my trusted sites list in Internet Explorer.

When on the page you want to add to the trusted list:

Tools --> Internet Options --> Security --> Trusted Sites --> Sites

Might be different depending on your version of IE or if you use a different browser.

I have worn my 305 under my swim cap many times in OW and have never had a problem with it measuring distance (at least consistantly.  The only issue I have ever had is not actually  hitting the start button because it is under my cap and I can't see it.

Being able to wear on my wrist with the 310xt would be cool but I would still be afraid to lose it.

My 15min 31sec open water swim of 800yd this morning was logged as 1.31mi. The jitter was pretty extreme - probably as bad as what I've seen published on using the 310XT before the new feature was implemented in v2.90.

I had good satellite accuracy (+/-21ft), confirmed firmware v2.90 is diplayed in About Forerunner and have Mode, Other, Settings, Other Settings, Swim, Eanbled=YES.

Unless I did it wrong...

After 2.5 hrs of working on getting the update last night, I finally found the correct series of work around to get it loaded.  I had to be on the page for the update, then add buy.garmin.com to the trusted sites list (or I couldn't get there if I added it earlier).  Then when it asked if I wanted to display all content, I had to choose NO to actually get the download link to work.  Then I had to download it 4 times before it loaded in the ANT agent.  But it works now.

Did my bike ride today with version 2.9 and I HATE the GPS speed input.  I loved having the GSC-10 display my speed because it was smooth and reacted fasted to actual changes.  Does anyone know of a work around to get teh speed back from the Speed/Cadence sensor instead of GPS?
