Micro SD cards - so which ones actually do work?

simcity 1 month ago

Hello All,

So clearly there is some *very* finicky firmware in these units and getting micro SD cards recognised is complete and utter pot luck!!

I've tried a box fresh Sandisk 512GB Extreme Pro card with zero success, despite formatting it in every format and cluster size known to man. Tried (re)inserting the card with the unit powered off and powered on. Make no odds. Just not recognised at all. Card itself is totally fine and checks out in ValiDrive et al.

Therefore before I get into testing the other bunch of SD cards I have kicking, I just wanted to ask quickly to save hours of grief...

What micro SD cards actually *do work* with the wonderful firmware Garmin's engineers and software subcontractors have foisted on us ;-) ?

(GPSMAP H1i Plus running v6.04)

Ta much

Thanks for this thread, I've been super frustrated. I've been talking with Garmin support for over a month. First they said it's my problem and they had larger cards working, then we exchanged devices…

I've formatted mine in exFAT (using the defaults of the SD Memory Card Formatter by the SD Association). I think exFAT is even required for microSDXC cards, but not sure if the H1 complies with SD card…

I have reported this issue to local (Netherlands) support, but haven't really had any response to it. So not sure if there's actually a ticket for this issue.

But I fully agree that anyone commenting here and experiencing the same issue should report it to Garmin support. The more reports the more likely the issue gets investigated and eventually fixed.

I guess it's a bit of a downside of the outdoor handheld products, there are simply fewer users compared to like Fenix 8, so less people that will report if there's an actual issue. Aside from the fact that many of the issues we report here should have been caught by Garmin themselves in the first place...
