This is a universal phone holder for the VW Golf MK6 with the RCD210 radio. It fits in the tray beneath the display. The clamp of the holder is a remix of the rotating clamp from the Modular Mounting System from yyh1002.
The Version 2 of the Clamp has a cutout and mounting holes for a spring. It can be mounted with two M3 bolts and square nuts.
If the fit between the clamp and the rotating mechanism comes loose, a self-sticking felt pad can help to fill the gap.
