Metal tab blocks magnetic charging
The set screws are too small and they do not have an adapter that fits the magnet charging rings on the newer phones

My favorite BMW car mount.
This is my favorite mount for BMWs. I have them on two cars (X4M and a 328), but I always modify the mount and install a metal ball (purchased here on Amazon) so I can mount an ESR Wireless charger. This combo is the best charging mount and system I have ever tried

sturdy mount nice fit
fit nicely and magnet is strong using the included metal disc to put inside phone case. was missing instructions but figured it out. you have to screw in the small set screws until it is snug. using a longer hex key made it easier.
