Thread: Which is the limitation to the SD/microSD card size for Garmin devices ?

Well, 'Garmin is Garmin' after all and we've grown used to their foibles i guess. Not a hill o'beans compared to their using us for beta testing of software and firmware though.

As to my personal experience: I'm using Kingston 8GB class 10 micro SDHC cards (with standard SD adapters where needed) in my two 205Ws, 660, and 3760. All work just fine with the full CN NA NT mapset (currently at 2015.10).

My nitpickin' follows: Maybe a typo to lump 660 in with the other nuvis? Series 2 and 7 got firmware upgrades in recent years to remove the 2GiB FAT16 file size limit for images on SD cards and also to allow a second map gmapsup1.img on cards, but unless I slept thru it for them [quite likely, channeling Prof. Farnsworth lately], early SPs and Series 3 & 6 nuvis are still stuck with the 2 GiB file limit. 2015.10 NA ALL is 2.16 GiB (2,329,477,120 bytes)

EDIT: Apologies Mr. Natural, you haven't made a typo it seems. As i've now seen other reports that users were getting NA All 2014.40 to work on 3xx/6xx units, in spite of it being 2.10 GiB and well over the 2Gib limit, I've done an experiment and found that it does in fact load and work on those [supposed] 2GiB limited devices. I'm a little confounded by this and it defies explanation. The 2.16 GiB 2015.10 as expected doesn't work. Why one and not the other? Anyone able to explain this?
