Garmin In Reach, or another recommendation

I just fired up the Garmin application on my ipad nav tool and zooming in below a certain point over the Yukon Territory you loose details. At the lowest upper zoom level it shows roads (crude, squiggly lines) and what appear to be forest boundaries, one step closer in and the roads and those boundaries all go away.

In contrast, zoomed Gaia is showing city streets and individual buildings in Tuktoyaktuk. So I'm going to guess that for decent detail up there in Garmin that you're going to need their add-in maps.
 
I have an InReach Mini for SOS and updating my loved ones as needed, and run Onx in offline mode my cell phone for navigation (doesn't require cell service), since I already carry the phone for ballistics. If I were trying to eliminate carrying the phone I would get an InReach Explorer, but I'm not sure there are any actual weight savings by doing so. I also carry a portable power pack to charge the phone and GPS as needed.
 
You have to have a subscription for the Garmin. If you would just like the emergency satellite location feature, look into the an ACR PLB
 
I am wondering if I need to purchase the separate maps (for about $86 each) in order to have good topo maps of Western Canada (the Yukon specifically)? Does anyone know?
Now that I used the InReach Mini on my Yukon hunt, in the most remote areas, I can report it functioned very well. It showed us crude topo maps that were adequate (no additional maps need to be or could be purchased). Sending texts to our wives and loved ones worked very well, and also let us communicate with the outfitter who was 20 hours away by horseback. I was also able to follow the path my stepson was following as he hunted with his guide.
Luckily, I barely escaped needing the emergency rescue feature when my horse suddenly slipped onto his left side on a large slick rock, with my left lower leg catching the full weight of the horse. Fortunately, by boot came out of the stirrup when the horse quickly jumped up on his feet. I did suffer a very painful swollen left calf which kept me in spike camp for 3 days, after which I was able to resume hunting. Needless to say, having the emergency rescue feature available was quite reassuring, especially since I had the foresight to purchase the rescue insurance before the trip (for approx $35).
We deactivated our subscriptions upon our return home, but are ready to reactivate it for our next wilderness adventure.
The only negative: one needs a portable solar panel connected to a backup battery pack, and lots of sunshine, to permit recharging each night.
