Just paid $100 for this microSD. Only instruction on using it is "see your user's manual at garmin.com." The "support" page asks for the product description or serial number. I've typed in every string of text or number on the packaging, none of which are found. There appears to be no place on the Garmin site to contact a real support person. The packaging does say "just plug into compatible device," but doesn't say if my Monterra is compatible. I've read online that I should not write to the product microSD because doing so might ruin it. So, not knowing if the Monterra will one day write something to it I'm reluctant to plug it in.
Unfortunately, I'm leaving for Zion tomorrow :-(
I should say I'm not exactly a newbie here. Been using Garmin stuff for year, and just a few days ago managed to get the 24k West installed on Windows 10 machine BaseCamp, then onto a 2Gb microsd card that works when plugged into my Monterra. But why is loading maps on Garmin devices such an ordeal?
