After copying new software onto memory card with help from garmin support , I tried to install software into the 1022 . I turned unit on let it boot up , installation instructions followed , the unit never gave me the selection to 'update software'. It gave me a selection of ' Manage card or copy built-map or set activecaptain card. scrolled thur those prompts . It then gave ' file type ADM or another file type which I didn't write down on that screen it also had save to card, merge from card replace from card or delete file. also gave me merge from selected file and replace from selected file. I am not sure what to do ,being that garmin support are off today , I thought about getting help from people that actually use Garmin .
