Pair your Bluetooth devices with a simple shake of the 20S EVO. The 20S EVO now features premium HD speakers. The 20S EVO was designed with a fixed type, shark fin antenna as opposed to its predecessor with the flip up antenna.
Easy to install (on my Arai Tour X4 skid lid) and to use.
Good battery life.
As well as speakers, it also allows one to plug in some ear bud headphones (via a 3.5mm jack) built into the unit.
The in-built radio is a handy feature as is the ability to simultaneously link the unit to ones phone and a GPS..
