Total system failure / Bootloop after enabling "Activity" map layer – My patience has run out

I’ve officially reached my limit with this device. I’ve spent the last few weeks testing it, trying to be patient and give it a fair chance despite the bugs. I really wanted to love it, but the latest firmware seems to be a case of "one step forward, two steps back."

Yesterday, the device completely gave up on me. After simply enabling the "Activities" map layer, it entered a constant bootloop.

The most frustrating part is that the device is now completely unresponsive to any recovery attempts:
It won't stay off: When I power it down via the menu, it automatically restarts itself.
Reset is broken: Selecting a factory reset triggers a reboot, but nothing actually changes – it starts back up with all my old data and the same loop.

Activity crash: If I try to stop or save an activity, it crashes and reboots immediately.
Buttons are useless: A long press on the power button does nothing to break the cycle.
I can't help but shudder at the thought of this happening during a real trip. If I were out in the field, relying on this for navigation, I’d be in serious trouble. It’s incredibly disappointing that a tool meant for reliability can be "bricked" by a native software setting.

Is there any way to force a "nuclear" master reset when the menu options fail? Or is this now just an expensive paperweight? Any help would be appreciated, as my trust in this unit is currently at zero.
This is my latest Garmin device.

  • i overcame my boot loop by pressing page, enter, page, enter, …… till some massage popped up. Please search for my post. I suspect that the problems came from outdoor maps plus maps. When i removed them, I had no more boot loops

  • In my case, the issue was triggered by enabling the "Activities" map layer. I had 3 activities selected that I wanted to see on the map. As soon as I toggled them on, the device went "crazy" and fell into a constant boot loop. Once I managed to deselect those activities, the boot loop finally stopped.

    Regardless, the unit is already listed on an auction site, waiting for a new owner. This device simply no longer inspires any confidence. I am officially done with Garmin handhelds. I don't explore extreme terrains anymore, and a smartphone is more than enough for my needs.

    I’ve owned the entire GPSMap series: 60Csx, 62, 64, 67, and now the H1. I’ve reached my breaking point. How long can one act as a "free beta tester" for Garmin’s broken software? Enough is enough.
