RAM Mounts products are super-high functioning
These mount under the bottom stem bases of the side mirrors and allow professional mounting of treasured farkles such as phones, GPSes, and other devices. The way you set up your base mount connections will handle everything that you add later. Lots and lots of options with RAM Mounts -- excellent.
