I got a ubiolabs universal wireless car mount in Costco – https://www.ubiolabs.com/product-page/universal-wireless-car-mount
After a while the base for it broke, fortunately I have a spare suction base for a gopro mount, so updated an existing design – GoPro simplified clip mount by cperiod to use as an adapter
