I use a middle size magnetic Road Gear map holder. I relocated 1 of the magnet sets lower/ center. I used 3 electrical box knock out plugs, held onto the glove box lid with 3M automotive trim tape. Yes the bars will hit it at full lock but does not dislodge it. ANY THING that touches / rides on the paint on this bike WILL remove the paint. This set up has been working for me for 30,000 miles. Has stayed in place at 115 mph.
