Hi, last year i bought SD card 2016/2017 Europe on Ebay.
At beginning it worked well, but few months ago i saw that i can not enter new location.
Change country sometimes help, sometimes not. Most of time Navi just crashes and restart.
I put SD card to laptop and when i put properties on folder inside i see it takes 96GB!!! I found the big folder with a lot of crap in it with strange dates and symbols.
Maybe somebody had similar issues? Or has 2016/2017 card's internals to format mine and try to upload it again?

Regards
