This is my solution for mounting my iphone on the handlebar area of my 2015 RT.
Parts needed: Mirror “C” mount from a BMW GS, RAM ball with thread, RAM D mount, and Quad Lock mount.
Mirror mount replaces standard RT “C” mount that fixes the brake or clutch assemblies. RAM ball comes with 8mm male thread, (need to confirm thread pitch as RAM have metric and imperial versions). Wunderlich also make a “C” mount for similar price.
Phone is stable and does not block instrument cluster. Fit left or right to suite.
