I just frankenstein this mount today and turned out great. The location of the mount is prime so I wanted to capitalize on that so my head & eyes aren't wondering down & away from the road.
The wireless charging cradle I already previously owned and mounts by a 17mm ball,
Yuechi BMW FXX Body Aluminum Phone Mount Trim as a base, robbed the
17mm ball mount arm from a Tackform Car Phone Holder Magnetic Mount. All of which were purchased through Amazon.
