I wouldn't say you are too stupid at all. I work in tech and have seen many times where something works for many and the same setup doesn't work for others, but no fault of their own. I know it sounds crazy, but I feel that it is common for this to be the case.
I still have my Mini 6, but I sold my Garmin. Now that the iPhone has the emergency satellite, I don't need the Garmin. But before I get shot down, I know the iPhone emergency service is not "robust" yet, for lack of better terms. It will get there though. I like not having to carry a dedicated device that only gets used occasionally.
