If you know someone who has a prime membership, you can get it with free shipping, in 2 days. Heck if you want, e-transfer me the cash and I'll order it for you, and you can pick it up downtown Halifax.
Yeah and given the back side that OP linked in the comments I think it's made to attach to something like this https://www.amazon.com/Garmin-010-10747-00-Suction-cup-mount/dp/B000F7857S so far a phone/gps for a car.
I, too, have a magnetic car mount.
It comes with two different-sized plates that fit nicely between phone and case (has not scratched my phone yet) and an adhesive pad if you don't have a case. Magnet is powerful and won't let go of the phone easily.
I hate air-vent mounts, so the best part for me is that the socket-side of the mount fits perfectly on a Garmin suction cup mount.
