Lamonster SpyderDock with Ram GPS Mount(with 12v CIG/USB)
This kit works on the Spyder RT all years and Spyder ST all years and RS and RSS from 2013 on. Will also work on 2013-15 RS and RSS
We recomend this one if connecting directly to the battery.
This Kit Includes: SpyderDock, 2" Ram arm, Ram 2"X1.7" base with 1" ball and all wiring + terminals to wire direct to the battery or to auxiliary power source.
This kit also has the 12v cig with dual USB insert. This gives you many more options such as heated gear, many different chargers (Phone's GPS etc.)
Also can charge your battery from this port (if wired direct to battery).
