I’ve been using this mounted to window and resting the arm on the dash. Pretty solid so far.

That's what I currently do with this dash mount. Vent mounts don't work well for me, I live in a place where I have to crank the heat in the colder months and it overheats my phone :( My '17 doesn't have built in CarPlay.
Pretty cool.
I've been using this one for the past three years, now for my V60 (dual screen). Gets the job done I guess. https://www.amazon.com/gp/aw/d/B076B27WP6?psc=1&ref=ppx_pop_mob_b_asin_title

It has never dropped my phone and the mount has not moved since I bought it 4 months ago.
Stuck to that little storage cubby up top.
I got a mount like this:https://www.amazon.com/iOttie-Dashboard-Windshield-Samsung-Smartphone/dp/B076B27WP6/ref=sr_1_1_sspa?keywords=iphone+dash+mount&qid=1563811807&s=gateway&sr=8-1-spons&psc=1 (which I think is the one you just ordered)
It was the sturdiest, most articulated one I could find. In the winter I stick the pad on the dash, to the left of that upper display, so that the phone is above the vent there. Right now it's too hot to do that, my phone gets too hot in the sun. If I lower it to the vent it's blocked by/in the way of the wiper lever. So, I have the pad stuck on that flat part in front of the upper display, but as far right as it can go (so it doesn't block my view of the backup camera). Then I moved the mount's arm to the right so that the back of my phone catches some AC, and swivel the phone to face me.
I know it's complicated but it's the best solution I've found, nothing else works very well. I haven't had any trouble with the suction cup.
Is it this one? https://www.amazon.com/dp/B076B27WP6/
