Garmin 7SV & Active Captain problem...

I bought a new boat with a 7SV on it last fall. I've been wrestling with the manual, discussions in various groups, and videos for setup and operation. I feel pretty comfortable with it, now, and love the contour mapping. 

The problem I'm having is in getting the contour maps into active captain on my phone. I was on the phone with Garmin support, again, another 1-1/2 hours Friday, they couldn't help. The tech insisted my unit has a card slot, which the 7SV Striker vivid does not...it uses internal memory and wifi. 

After charting, it shows that it uploaded my charts to the Garmin community, but when I go to "my maps" on my mobile device, it says I have to register my maps. I sync the phone with the plotter, it says ok and that my maps will be registered automatically. When I go to the Garmin Quickdraw Community to download, none of my maps are there.

I'm lost on how to simply get copies of my plotter's maps to my phone for backup. I want to buy a 9SV for another boat, but I'm not gonna do it if I can't back up / copy my mapping. Garmin seems to be unable to understand my problem. Besides seeing similar comments elsewhere, I never find an answer.

Do any of you know how to do this?

Thanks,

Dave
