I have a Garmin GLO since 10 years (so I guess this must then be the “GLO 1”) and it works / worked just fine with a number of iPads that I owned.
The only thing I needed the replace twice was the rechargeable battery. It’s a standard cell phone battery, so you get them at any cellphone repair shop for next to nothing - or get the ‘original’ from Garmin.
I think when it comes to non-certified navigation tools, redundancy is the name of the game. Like having two tablets, and a smart phone, that all can stand in for each other. And having different GPS sources, with different power sources.
