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
Simon

Update October 21, 2026: We have released SW version 13.08 that includes a fix for this concern. If you are experiencing this, and have not already, please install this update.
If you are still experiencing…
For The Garmin Response Team:
Get a GPSmap H1 and also get a Garmin GPSmap 66sr (or 67)
Mark a waypoint on both GPSmap units, let say 5 km. away. Now create a Route to that waypoint on both units.
Compare…
Hello,
I am experiencing the same problems with the altimeter plot. The plot shows the elevation profile ahead, but it disappears after a short while. This seems to be the same or similar problem as in this…
Thank you for this information. If this occurs again this next time, I would love to collect some additional details. You can upload these here: supportforms.garmin.com/.../
As far as I remember, when this happens, making zoom in the height chart screen helps. That is, when you zoom the chart more (+), the chart will reappear correctly. When you zoom out, problem returns.
'Yes' and 'No'; after a long (routed) hike this 'trick' won't work anymore on my H1. Meaning: it doesn't show the BLUE upcoming elevation plot at all ...
After reporting this issue to Garmin, a while ago, Garmin Support sent me a Ref.number so I guess Garmin will look into this issue ...
Let's hope it will be finally solved. On my GPSMap 66sr it works without any problem ;-)
I have the same issue. I can confirm that a restart / reboot (turn off and on again) fixes the issue but the forecast disappears again after a while. Eg I restarted mine 6 times during a 5k hike to keep it working which is not viable.
UPDATE: firmware 13.07 did not solve the problem for me.
Better luck next time ....
I am also experiencing the altimeter graph issue described in this thread.
The changelog for software version 13.07 states: “Fixed various altimeter page issues.”
Could Garmin clarify whether this fix specifically addresses the disappearing elevation profile during active navigation? If not, is this issue still under investigation?
For The Garmin Response Team:
Get a GPSmap H1 and also get a Garmin GPSmap 66sr (or 67)
Mark a waypoint on both GPSmap units, let say 5 km. away. Now create a Route to that waypoint on both units.
Compare the GPSmap H1 with the GPSmap 66sr or 67 and see what happens when you walk towards the waypoint. I can almost guarantee that you wil notice that, after a while, the expected Blue altitude profile disappears on the H1. When playing with + or - key or the rocker switch, sometimes the expected Blue altitude profile will show up.
The GPSmap 66sr (or 67) on the other hand, keeps showing the expected blue altitude profile without any issue ... You can use the + or - key or the rocker switch and still the altitude profile remains visible.
I'm just wondering, does the Garmin Response Team has the same experience when this was mentioned earlier and does Garmin also use the Garmni 66sr or 67 to investigate this problem? Does the Garmin Response Team test the mentioned issues in a field situation?
I'd never used navigation before (I don't need it), but after seeing that entry in the changelog, I wanted to try it specifically to test this issue. I see the same bug, and find empe's final two questions entirely appropriate.
I can confirm that this issue still persists after a factory reset and with the latest software version. The altimeter/height graph continues to malfunction while navigating.
Update October 21, 2026: We have released SW version 13.08 that includes a fix for this concern. If you are experiencing this, and have not already, please install this update.
If you are still experiencing this, please post here again.

So you didn't read empe's thread GPSMAP H1i Software 13.08 – Altimeter and Navigation Issues Still Persist, did you?
