They don't make technology like they used to.
I just found an old hand-held Garmin GPS device. It's at least 18 years old.
Takes 2 AA batteries, so no problem powering it. But it was stuck showing the wrong date and time from 2006, and no way to update that.
Garmin released an update for this device at some point that fixes this.
Their updater software from 2019 still works.
I found a mini-USB cable.
All updated and working fine!
Amazing. (And kudos to Garmin for the update)
