The toggle next to each map has disappeared..?

sloth1960 — Sat, 05 Sep 2026 10:43:13 GMT

The toggle next to each map and enables a map to be selected has disappeared.

I have a number of country maps, although I have yet to try the H1 in other countries, so I guess it might ‘auto select’ ?!

suggestions / ideas before I travel.

RE: The toggle next to each map has disappeared..?

This has indeed changed in one of the previous software updates.

Third party maps can now be enabled and disabled in the Map Layers menu in the Map app. Just select the Map Layer corresponding to your installed third party map. Optionally you can set the Map Type to Base Map but that’s not required to display the third party map.

RE: "Off Course" Data Field - Does It Work For You?

empe — Sat, 05 Sep 2026 07:59:48 GMT

I was using this feature today for the first time for a short hike of 20 minutes, just to try it out. It was always showing the deviation to the navigated route. The value was in the range of L5 to R5 meters, till I went off the route intentionally. Then the value was up to maybe 30 meters, till the route was new calculated. I will try out again on a longer hike.

"Off Course" Data Field - Does It Work For You?

Phoenix — Fri, 28 Aug 2026 10:45:28 GMT

I've been using the H1 for 3 months now, a couple of times a week.

Throughout all the firmware updates, I have never got this data field working properly.

I get a variety of behaviours. Most common is it appears for the first few minutes then just shows no data for the rest of the hike. Sometimes it just never shows any data, even at the start of a hike. Once, it showed no data until the last five minutes of a hike. Has always worked perfectly on 66 and 67.

I've opened a case with Garmin but they can't reproduce the issue. So, I'm interested if this data field works for other people. Good or bad, I'd like to hear what your experience is.

RE: [GPSMAP H1] Waypoint app stuck on waypoint averaging screen

Garmin - LF — Thu, 03 Sep 2026 21:26:30 GMT

Hello Barbara A. I was not experiencing this concern. When I used waypoint averaging, I was able to use the arrow to return to the previous screen. Then when I pressed mark, this marked a new waypoint. So if you are still experiencing this, I would love to ensure you have tried the following:

Powercycled the device.
Ensured the device is on the latest SW version, 12.08.
If there is no change, I would love to collect a video showing this concern here: supportforms.garmin.com/.../

[GPSMAP H1] Waypoint app stuck on waypoint averaging screen

Barbara A. — Tue, 01 Sep 2026 07:13:17 GMT

Hello all,

I just booted up the device for the first time and am getting to know it. I want to mark waypoints with "waypoint averaging" but when the averaging finishes I don't know how to go back to the initial waypoint screen. When the averaging reaches 100%, I click on "done", then click on the arrow on the upper left, but that brings me back to the apps menu (with map, compass, settings, etc.). If I click "mark waypoint" again, I'm taken to the waypoint averaging screen. How can I mark new waypoints after using "waypoint averaging"?

Cheers!

[Garmin H1] Can't find waypoints GPX in my computer's Garmin folder when connected with USB

Barbara A. — Tue, 01 Sep 2026 10:54:17 GMT

Hello all,

my company just purchased a new Garmin H1 and I'm getting acquainted with it. Since it'll be shared with different work colleagues, transferring saved waypoints through USB instead of Garmin Explore is much more practical. However, when I connect the device to my computer, I can't find the saved waypoints. They aren't in the GPX folder, Locations, Activities, NewFiles... They're nowhere. I can sync the points to my Garmin Explore account and get the GPX from there, so they exist and aren't corrupted. Why can I not find them in the GARMIN folder?

Thank you in advance.

RE: [Garmin H1] Can't find waypoints GPX in my computer's Garmin folder when connected with USB

Barbara A. — Wed, 02 Sep 2026 12:55:08 GMT

That did it! Not very happy about the fact that I can't choose which waypoints to export, or that we still need an AllTrails account, but this is a solution nonetheless. Cheers!

RE: H1 Navigation Prompts

5566905 — Tue, 01 Sep 2026 23:00:11 GMT

I am thinking about putting together a video showing all the various different ways the device fails. As a device that sole purpose is to act as a navigational aid, the H1 so far for me has been a complete failure and I am extremely disappointed that I have basically paid you guys to become a beta tester for your product. So far after nearly 2 weeks of use I haven't been able to complete a single hike where the device has worked correctly. I think it's bad also that there is a inreach version of this device which someone one day might rely on but won't be-able to use it because of some random bug.

I have given up trying to get the tones back without routing switched on so instead I have started enabling routing and making sure re-routing is turned off. Today I did a 13 mile hike and I was listening to what it was saying which was things along of the lines of "turn left in 3 quarters of a mile" if I was in a car this would be useful but I am walking so that takes a while to actually walk 3 quarters of a mile and then when I got to the turn --nothing-- just silence.

Then I got to many turns where the navigation prompt just did not work even though it was a 90 degree turn on a routable path.

For about 6 miles it would just go between giving me navigational prompts and then nothing, complete random I couldn't detect any pattern to it. I just know it would miss more than it would notify me about. But then I got into some woodland and it was just system tone every few seconds, no voice just making the system tone noise. I looked at the navigation guidance text and it just says "follow footpath" even though I knew many turns were coming up and again no notifications just random tones when walking on straight sections.

I then had to take a detour due to a tree that had fallen down and this is where it went really wrong as it seem to get stuck and distance to next point started increasing even though I had rejoined the route again.

I then stopped navigating and reloaded the course and then it was just directing me to the start of the route again even though I was already on the course only 9 miles in.

I brought this device because I wanted something reliable and something I could use with gloves but it seems extremely unreliable and I just don't understand how a device which is nearly a year on from release is in this state. I am thinking of just going back to my phone because even though its a pain to use in the rain and the battery drains fairly a quickly at least it works and I can rely on it.

I will have a think where would be best to do this video, I will just make a basically square and see if the device can even manage that, I doubt it can because its crap.

H1 Navigation Prompts

5566905 — Fri, 28 Aug 2026 00:49:34 GMT

I recently purchased a H1 and before powering on the unit I updated firmware to the latest 12.08 version.

I had a route that I had built using komoot and I had simply exported this and then imported this onto Garmin Connect to get it onto the device. I started the course on my H1 with Routing switched off as it's my understanding that if I turn this on then the device will try and navigate me around areas where there is no visible paths on the map and since I was planning to walk through some woodland I didn't want the device to do this.

I also didn't want the annoying sat nav women voice talking constantly because I had a fairly good idea where I was going. I headed out and when I reached a turn I would here a tone on the h1 and also a system message would appear which showed the message Approaching Point. I navigated through the route and sometimes if I was unsure about a turn after hearing the tone I would check the map and I was happy with this way of navigating.

On the final leg of the trip I started to find the alert message fairly annoying as it would basically bring up a pop-up which you had to click OK to to get rid off quickly and it would block the screen if you were looking at the map so I was looking through the settings to see how you could turn this off. I remember ending up in the proximity settings and I toggled this off and then continued on my route to then hear a tone. With no visible turn I looked at the device to see a message that I was off course.

I had missed a turn because there was no notification tone so reset the proximity settings and walked back to the course, I got a message that I was on course and heard the tone. Started walking again but this time kept the device out as I could see a 90 degree turn coming up in a few minutes. Got to the turn and there was no notifications, no tones, nothing. I stopped navigating and reloaded the course, started walking again and waited for another turn and again no notification.

I looked through all of the settings and I couldn't find anything related as to why the navigation tones had stopped working and I spent a number of hours trying to figure this out and even resorted to using AI but that was an annoying experience because it kept providing me with instructions for the GPSMAP 67 even though I asked it not to do this. Anyway decided to reach out to Garmin support.

I get the impression that the support guys are aware that this device is fairly crap as the solution offered pretty much straight away was to reset the device. I did this but opted to not connect it to my phone or wifi as I figured that these kinds of devices most likely store setting files in the cloud. I copied my route over via USB and tested again and everything was back to normal and I could hear the navigation tones when coming up to a turn.

Figured the issue was resolved and waited for a day to try and get my local settings file to become the primary file and not get overwritten by whatever was stored in the cloud. Connected my phone again as I want to be able to get routes onto the device without having to plug it in and started my route again and from the start the navigation tones were not working.

Clearly the settings stored in the cloud had taken priority and had overwritten the settings on the device. I did ask Garmin support about this and I was told that when I was adding the device using garmin explore I would be given a prompt about if I wanted to restore the settings or not. This turned out not to be true so I am guessing the support guy just didn't want to help the latest idiot to buy one of these devices and told me some BS to get rid of me. I went through all of the settings again and I couldn't see what the problem is or any difference to what the settings were before.

One observation I have found while using the device which I think is fairly poor is why there seems to be a settings menu and then if you press the magnifier at the bottom right then then allows you to access the same settings but then with additional extra settings listed. Why not just have everything in one place? it's fairly confusing I kind of found it by accident because in here you can find a setting for turn warnings which I have turned on but in the settings you enter just by clicking settings on the main menu this option does not appear. The navigation settings should also be included under the main settings menu also rather than hidden away.

Another observation is why the device allows you to walk about 250-300 meters off course before notifying you that you're off course. Surely a more sensible figure would be around 50 meters and there should be a setting for this also in the options so you can configure how soon you will be notified, maybe there is but it's just hidden away under some random menu that I haven't discovered yet.

My final observation is that the odometer does not work on my device, it's been stuck at 6.24 miles even though I have walked about 55 miles this week and that's after the reset. I think there are two fields for this one which reads zero and another one which is trip odometer and that's stuck at 6.24 miles. I ain't to bothered about this as I don't care about stats anyway but it's just something I noticed as I didn't bother reconfiguring the dashboard after resetting as I figured I would most likely end up resetting the device again anyway so it was there by default.

If I go to my route and enable routing I see the calculating thing and then the annoying sat nav women starts talking. I have also noticed that in my courses list I will see that some have been duplicated I assume this is because when I have enabled routing the route as been modified to stick to known paths or maybe it's just adding extra information into the file so it knows where the turns are.

Either way I would much rather have 100% confidence that the route I am following is the one I created and not one that a computer has decided to take me around because it's considered a popular route based on heat maps or whatever and additionally I would love to have my annoying system message pop ups back because I really can't stand the sat nav women's voice.

I am using the talkytoaster maps which are routable, sorry Garmin but your base & premium maps are rubbish in the UK. The same issue applies no matter which map is used.

I have tried unregistering the device from my account and waiting a day in hopes that the local settings will overwrite those stored in the cloud.
I have tried toggling off sync with garmin explore before pairing with my phone but this still resulted in my settings being overwritten and I could only see that waypoints and courses were not transferred.
I have sound on, I hear tone when I am 250+ meters off course!
Under Turn warnings I have early turn warning: Time alert & Final Turn Warning: Distance Alert.
I have Course Transitions set to AUTO i did try manual but I think the setting just controls the compass.
Nav. Prompts is turned on under Sounds & Vibration
On Garmin Connect I have made sure that when importing a route I have selected Hike and I have made sure that Turn Notifications are turned on.
I have tried creating a route using Hiiker, same issue.
I have tried creating a route using garmin explore, same issue.
I have tried creating a route using basecamp, same issue.

Does anyone know how I can get these turn tones back or how I can overwrite the settings stored in the cloud with those from a device that has been reset?

Thanks

Hi, thank you for answering. Unfortunately, we are not allowed to download BaseCamp in my organisation. That's why I'm really interested in a USB solution. I've seen a .fit file in the GARMIN folder, but when I used an online fit-to-gpx converter It came out empty...

RE: [Garmin H1] Can't find waypoints GPX in my computer's Garmin folder when connected with USB

3768946 — Tue, 01 Sep 2026 15:14:06 GMT

Waypoints are saved as .fit files in the Location folder. To save the files as GPX, the quickest and most practical method is to open BaseCamp with your device connected. You will see all the waypoints and can export them as GPX, either individually or grouped together.

Altimeter/Height Graph not working

Hi,

since I got the device, the altimeter graph is not working while navigating. Update to 10.13 did not change this.

Does anybody still have the same issue? Any way of workarounding it? Garmin, any plans for fixing this?

Cheers, thanks

RE: Altimeter/Height Graph not working

Forgot to mention I also uploaded the planned route (the one with a name) and the recorded activity (just a timestamp), both as GPX file.

RE: Altimeter/Height Graph not working

Simon — Sat, 29 Aug 2026 21:02:04 GMT

Hi,

I installed the latest update and did a quick test and it happened again. I planned a route and navigated it. In the beginning, the graph was fine, showing the part I already did and the upcoming part in blue. But after a while, the blue part just disappeared. When opening the altimeter view, the detail view of the upcoming part also has not been displayed. When I moved the selection in the overview part though, it reappeared. Anyways, when switching back to navigation view, the preview was still missing. After going on for a while, it reappeared.

For me it looks like there is something in the to-come altitude data which the widget cannot display. Hence, when I moved past that point, the widget worked normal again. But this is just a theory.

I documented it by photos and videos which I uploaded to the URL you posted. Also, I uploaded the Garmin folder, but I deleted the large files.

I hope the information I provided helps investigating and solving this issue. Let me know if you require more data.

Thanks a lot for your help, cheers,

Simon

RE: GPSMAP H1 firmware 11.07 does not recognize SanDisk Extreme Pro 128GB microSDXC, while 32GB card works

1917994 — Fri, 28 Aug 2026 14:48:38 GMT

A problem with fat32 is the max file size is limited to 4Gb, which could limit additional maps. But really, exfat has been around for 20 years and NTFS for longer, so there’s no excuse for compatibility.

I agree with your comment that there should be in-device formatting to ensure formatting is exactly as the devices require, but let’s face it, this is a Garmin software/hardware failure. The marketing hype is quite shocking as they must have known it didn’t work.

GPSMAP H1 firmware 11.07 does not recognize SanDisk Extreme Pro 128GB microSDXC, while 32GB card works

Clawsson — Mon, 10 Aug 2026 20:51:25 GMT

Hi,

I am experiencing a reproducible microSD card compatibility issue with a Garmin GPSMAP H1 running software version 11.07.

According to Garmin’s specifications, the GPSMAP H1 supports microSD cards up to 1 TB, so a 128 GB microSDXC card should be supported.

Device

Garmin GPSMAP H1
Software version: 11.07

Card that is NOT recognized

SanDisk Extreme Pro microSDXC
Capacity: 128 GB
The card itself works normally on my Mac and is fully readable/writable there.

Card that IS recognized

SanDisk Extreme Pro
Capacity: 32 GB
This card is detected correctly by the same GPSMAP H1.

This comparison strongly suggests that the microSD slot itself is functioning.

Formatting/tests performed with the 128 GB card

The card was initially formatted on macOS using Disk Utility.
File system: exFAT
Partition scheme: Master Boot Record (MBR)
The physical card and partition were verified in macOS Disk Utility.
Terminal output confirmed an FDisk_partition_scheme / MBR partition table.
The card was correctly mounted and accessible on the Mac with approximately 127.97 GB capacity.
I then reformatted the card again using the official SD Memory Card Formatter from the SD Association, using Overwrite Format, to rule out a macOS formatting issue.
After formatting, the card was properly ejected from macOS.
The GPSMAP H1 was powered off before inserting the card, and then powered on again.
The 128 GB card is still not detected.

Behaviour on the GPSMAP H1

With the 128 GB card inserted:

The device boots normally and does not indicate that a memory card has been detected.
Under Map Manager → Outdoor Maps+ → New Map, only Name and the available map layers are shown.
There is no “Storage Location” option.
Pressing the MENU button on that screen returns “No options”.

With the 32 GB SanDisk Extreme Pro card inserted, the device recognizes the card correctly.

Garmin Express test

I also connected the GPSMAP H1 to my Mac with the 128 GB card installed and opened Garmin Express.

The GPSMAP H1 itself is detected and connected correctly.

However, under the Removable Media tab, Garmin Express displays the message asking me to install removable media in the Garmin device. In other words, Garmin Express does not see the inserted 128 GB card either.

This means the 128 GB card is not merely unavailable to Outdoor Maps+; it appears that the GPSMAP H1 does not detect the card at all.

Summary

GPSMAP H1, firmware 11.07
SanDisk Extreme Pro 32 GB: recognized
SanDisk Extreme Pro 128 GB: not recognized
128 GB card works normally on macOS
Tested as exFAT + MBR
Reformatted with the official SD Association SD Memory Card Formatter using Overwrite Format
Inserted while the H1 was powered off
Not detected by the H1
No “Storage Location” option under Outdoor Maps+
Not detected as removable storage by Garmin Express

I have found other reports in this forum describing very similar behaviour with larger microSDXC cards, including reports specifically involving SanDisk Extreme Pro 128 GB cards.

Could Garmin please confirm whether this is a known compatibility or firmware issue with the GPSMAP H1?

Since Garmin officially specifies support for microSD cards up to 1 TB, I would also like to know:

Is the SanDisk Extreme Pro 128 GB supposed to be supported?
Is there a known issue with certain SDXC controllers or cards larger than 32 GB?
Is Garmin currently working on a firmware fix?
Is there any additional diagnostic information or log file I can provide?

I can also provide screenshots from macOS Disk Utility, Terminal, Garmin Express, and the device menus if useful.

Many Thanks.

Cheers, Ralf

Bedankt voor de uitgebreide test, het vreemde is dat het navigeren voor update 12.06 het prima deed. Er is volgens mij nog geen reactie van Garmin, voor deze best wel flinke bug.
