The 2 options that have been discussed most here are the aluminum piece that snaps on the passenger L.H. grab bar (which fits between the seams) and the holder which fits into the cigarette lighter. What i wanted was a mounting surface which would accept both my LG V20 phone and my Zumo 660LM. I bought this on Amazon: https://www.amazon.com/dp/B072VGDDC8/ref=nav_timeline_asin?_encoding=UTF8&psc=1 It works for my purposes. It doesn't interfere with the lighter popping open and it's not unsightly with nothing mounted.
