After updating to this newest version, GE not recognice sd cards in a satnav. So no posibility to install maps directly on sd in place of Zumo.
This is also in the windows version.
Nor does it on my BMW Motorrad Navi V! There is a 64GB card installed (msdos, not exFAT), 90% empty, and Garmin Express says "No memory card found. Please insert a microSD card with at least 5GB free (max. 64GB) and retry" (roughly retranslated from German)
Unfortunately its not. The card came as exFAT, but I re-formatted it as FAT, now MacOS mounts it as msdos (as I mentioned). And it gets seen by the Navigator itself, as the old map is on it (installed by some older version ofGarmin Express!). Even Basecamp sees it as a "device" with the Map data on it...
FAT16 can only adress 4GB, therefore a FAT filesystem over 4GB is always FAT32. And, as I already mentioned: The navigator and former versions of GarminExpress had no problems using the card...
VespaMarc's original post implies this is only after upgrade to 4.1.27. I can confirm that it worked with exacly this card with former versions of Garmin Express.
According to the Wikipedia article on FAT, FAT16 is limited to 4GB. There is an extension FAT16B which allows to redefine sectors to have 4KB (shudder!), thus adressing up to 16GB. FAT32 has a limit of 2TB (8TB with 4KB sectors). FAT32 is used in opposition to exFAT (which isn't FAT at all). But that's purely academic, as the problem lies in a different corner: GarminExpress not being able to recognize SD-cards AT ALL in this version. I just tried a 4GB card to no avail.
Can you perhaps contact someone at Garmin on this topic? I tried a Support Escalate Form, but it crashed on step 4:"Complete" :mad:
Glad you got through, hopefully the Express team will see this thread anyway.
As for the FAT issue, FAT32 can only handle files up to 4Gb in size. It's one reason why the EU map may cause issues shortly as it's pushing the 4Gb limit. I agree it's strange that a previous card that worked with Express now doesn't, but I'm unclear whether Express may fail if the card isn't FAT32. Guess you'll need to wait for the Express team.
As posted, 4.1.27 worked perfectly on my Win machine, installing the map to a 32Gb FAT32 formatted card.
After several days of mailing to the product support and getting unsignificant answers (mostly telling me to do something I did already or asking something I wrote in the mails already) I finally called them and got some guy who said:
BMW Motorrad Naviagtor + GarminExpress 4.1.27 + SD-card = DOES NOT WORK for some unknown reason.
He sent me a link to an older version, which has worked for somebody else but unfortunately doesn#t work for me.
But GarminMapinstall can install a subset (depending on free space of the internal memory) of the map. It is listed in myMaps now, but GarminExpress still complains about an existing update...
BTW: I was talking about max. file system size, you were talking about max. file size
