Moving from a Garmin 810 to a Garmin 830

About 5 years ago, I decided I needed to buy myself a dedicated bike computer, rather than the phone I’d been using up to that point. Primarily this was so I could ride for further since my phone generally died after a couple of hours of constant screen and GPS action. I went for the Garmin 810.

In a sense the 810 was a step back from a phone with its tiny screen and washed out colours, but I grew to love its turn by turn navigation, even if it was also the cause of my major annoyance with it, the occasional crash that only seemed to happen when using the turn by turn navigation.

But recently the USB socket packed in, my computer no longer recognised the Garmin when I plugged it in. Although I could still download ride data via my phone’s Bluetooth connection, I now had no way of uploading new routes to the device, so decided to treat myself with a 830. Those crashes had put me off Garmin devices somewhat but when I compared what was available from other companies, I came to the conclusion the 830 still looked like the best choice.

So this is a mini review of how the world of Garmin has moved on in the last 5 years and whether an upgrade is worth it.

On first sight, the 830 looks fairly similar to the 810 with almost exactly the same dimensions. The buttons have moved from the top to the front of the device which makes it rather difficult to press them if the device is mounted on your stem. Because of this, I’ve switched to using the out front bracket which is thankfully included with the device.

It’s when you turn it on, you start to notice the differences. The screen has a much higher resolution and the colours are much improved over the 810. The software should be familiar to anyone who has used an 810, but there have been many small tweaks and changes. Moving around the screens is very responsive and I’ve had no problems when wearing gloves.

I remember when I bought the 810, only a very basic base map was provided. I could buy a proper map from Garmin or try to figure out how to download OSM maps and install them. I went for OSM maps initially but eventually bought Garmin maps in the vain hope it would fix the crashes I was experiencing. Now the 830 comes with its own maps

Integration with my phone has moved on since the 810. I can now get routes directly on to the Garmin via the Strava app, rather than having to download from Strava and upload to the bike computer. I even get notifications from my phone appearing on the Garmin. Admittedly I’m generally on my bike to get away from these kind of things, so this may not be something I leave enabled, but I can imagine it would be useful when trying to meet up with someone.

I was always a big fan of turn by turn navigation. This has been improved so that when I go off route, the 830 will recalculate the route, even if this often just means telling me to make a U-turn. I even get told about sharp corners ahead. it can get a bit confused if a route covers the same bit of road more than once, trying to send me the wrong way, but it figures it out fairly quickly.

I’ve had the 830 for just over a month and ridden just over 300 miles. In that time I’ve had zero crashes. I wouldn’t like to say the software reliability problems of the past are gone (since crashes seemed to happen more frequently on longer rides which I’ve not really been doing due to the winter months) but I’m feeling more confident than I did with the 810.

I think the only complaint I have about the 830 is a problem I have with most bike computers, the price. I have a Garmin sat-nav for our car which provides pretty much the same functionality as the 830, but for a quarter of the price. There are differences in the software and the 830 integrates with heart rate monitors and power meters, but can such a vast difference in price be justified? I guess if this keeps going for five years, then maybe it can. Either way, I’ve been very impressed after my first month

Converting Strava segments to FIT files

Strava Premium users who own a Garmin can sync their favourite Strava segments with their Garmin device automatically. But that’s not an option available to free users. Apparently this site used to be able to generate the FIT files used by Garmins but Strava made some fairly radical changes to their API that broke that site (and many others).

So I’ve added a FIT file export to my Segment Explorer. Due to rather inclement weather I’ve not been able to test this out on the road yet, but downloading the FIT file and shoving it in my Garmin\NewFiles folder displays it in my Segments list so it seems to work. If you authorize my app then your PR time will also be included in the file.

Update – You can now add a goal to the generated FIT file if you generate the file from the segment details page

Recovering data from a crashed Garmin 810

I love my Garmin and it would be a perfect piece of tech if it weren’t for one problem. Almost every time I use it to follow a course, it will die at some point during the ride. I can turn it back on and after several minutes of confusion it will figure out where it is and I can resume recording. The suggestions on the Garmin forum mostly seem to be to downgrade to an older version of the firmware, but I’m too lazy to do that and keep hoping Garmin will fix it at some point.

But they haven’t yet, so I just live with it. So I thought I’d document what I do to recover the data from before the crash. When I plug the Garmin in, the data from after the crash will sync to Strava but it will also complain that something failed to sync. So the first thing to do is to manually upload the pre-crash data to Strava. This will be a .fit file in the Garmin\Activities folder of the device. Strava seems to be able to cope with the file, even though the Garmin sync can’t.

You may be happy enough just doing that, but I like to have an accurate record of my rides so I want to merge the two together. So I now

  • Export the two activities from Strava as GPX files.
  • Open them both in this tool.
  • Select both files, right click and merge them
  • In the newly created file, select both tracks, right click and select Restructuring/Join
  • Save the new file
  • Delete the two original activities from Strava
  • Upload the newly created file to Strava and feel satisfied with all the PRs I’ve hopefully achieved…
