Hi, with a bit of thought and improvisation i made a mount that is both extremely functional and instantly available/ removable.
I purchased a magnetic phone holder that is also a wireless charger, i fashioned a piece of flat spring steel from the blades of a large bulldog clip and then covered the clip with a finger from an old leather gardening glove.
i then drilled a hole in the clip and then screwed this to the mount with a small self tapping screw
the power comes from the usb in the glovebox and the mount simply slides onto the glovebox lid.
