Garmin Ultra2 102sv and maps ...

Hi everyone,

I got question here ... as i have just bought this Garmin Ultra2 102SV, it came with EU basemap only, would like to add a SD card to unit with locked Bluechart G2 map with .UNL file, which is using card's CID key.
Will this work ?

According to my latest knowledge - everything was set tight Garmin side, now new maps use some extra protection with UNL + GMA + GMS and .nTAG files and tie to ActiveCaptain app.
Is it possible the "old" way or is now-days only way >> buy maps?
if anyone has an idea how tro make G2 map work locked with card CID key to UNL file or otherwise ... PM me instructions , and if possible original card content of filenames , will help too (including hidden .nTag etc filenames
