I had been using a proclip dash mount for my Note 3 until I got the S7E. VERY secure, hasn't moved in years, and it's mounted in the grooves of my dash right in front of the AC vent, easy to install and very stable and unobtrusive. I bought the
Samsung wireless car charger to go on the proclip mount. The ball socket on the proclip mount fit perfectly into the charger. Very excited that it fit since the mount that came with the Samsung charger is suction (and large) and I don't like using suction mounts.
You can get a proclip mount custom for your vehicle and the wireless charger to put on it instead of a proclip holder, and you can buy a ball mount adapter plate from proclip as well.
And by the way, I'm really loving the Samsung wireless charging holder. So easy to put in and get out quickly, the sides squeeze in effortlessly and there's a quick release button when you want to take it out. The charge wasn't enough to charge it at first, but it was a real slow trickling drain. Recently I've been reading the battery life threads and turned off ok google detection among other things and now with the screen on it will charge, but super slowly (better than a slow drain).
