Well after a week or so of messing around with the Course Motorsports Charging Magnet Mount, I have given up on that and I am strictly using the Auto-Grip closing phone mount by Course. I'm sure the Magnet Mount works great for smaller phones, but I have the S21 Ultra which isn't exactly a small phone. I tried several different positions for the phone to contact the magnet mount but it would charge for 2-3 seconds and then would say wireless charging is disconnected. I tried phone with case and metal halo just under my cameras, I tried cutting out the back of my case on the inside of the halo ring hoping that would help the coils in phone make connection with the charging magnet mount and I also tried without my phone case on and all resulted in the same error. When it would work it was great, but trying to find the EXACT spot where the phone would have to sit was tiresome. I've moved my phone 10 times before finding a spot where the phone would actually charge. As much as I love the magnet mount as it's a little smaller then the auto-close mount/cradle and less intrusive it just wasn't worth the headache. I'm so glad I ordered both types of phone mounts, as I wasn't 100% sure it was going to work with the magnet mount but I did give it the good ol' college try.
My take on the magnet portion of the mount is that it's amazing and I've got some bumpy roads in my travels. The phone never once fell off and basically no vibration or shaking of the phone. So as a magnet for me, it works awesome. As a charger not so much. I would still recommend the magnet charging mount for those with smaller phones, large plus sized phones can be finicky and frustrating.
Now, the auto-grip mount is very nice as well, it's definitely smaller then other grip style mounts so it's not to bad. Doesn't cover up my start button and also doesn't cover up the vent either. The auto-grip closing feature works great and 100% of the time my phone starts charging right away. The sensors on the sides that detect you picking up the phone opens up the grips automatically and that also works without any flaws. Overall I really do like this auto-grip closing mount, just like the magnet charging mount the phone has very minimal shaking on roads and I can still read the screen/navigation maps on my phone. I've had windshield mounts and cup holder mounts that shake too much for my liking. So I am very pleased with this.
I highly recommend Course Motorsports phone mounts for anyone looking to add wireless charging or those who don't like the factory wireless location. I didn't have the factory wireless charging and I did look into it but it was going to be WAY more expensive and a lot more work to install. More importantly I don't like the location, way under the 12" screen. Course Motorsports mount puts it in view so your eyes are not off the road and I can use it for maps or just to see quick alerts sent to my phone without taking my eyes of the road.
My suggestion is if you have a rather large phone (comparable to the Samsung S21 Ultra) I would go with the auto-grip mount as it's the safer bet. The charging magnet mount works better for smaller phones, I tried it out with my work phone (Samsung S10) and it picked up the charge no problem. Larger phone I guess means large surface area for the coils inside phone, and since the magnet mount is only a small 2" or so disc I guess there isn't enough surface area. Maybe a rectangle shaped one would be better for large phone.
Anyhow just wanted to give a little update to help some potential buyers out.
I do prefer Course Motorsports vehicle specific mounts over ProClip, I feel it's a cleaner look and a better overall design. As the metal bracket slides down into a "slot" behind the radio trim so no chance it can slide down. But I don't think you can go wrong with either as ProClip also has positive reviews all over the place.
