This is an excellent device for use in UTVs or in boats. This is an audio interface that uses Bluetooth technology to connect to your smartphone and allow you to play whatever audio you prefer to listen to. This is the same size as marine rocker switches and snaps directly in the dash mounting hole. So you don’t have to install a full size stereo. You will need an amplifier and a pair of speakers. Connect the amplifier via the RCA outputs and the amplifier signal wire to control the amplifier on/off. Connect speakers then to the amplifier outputs and you are in business. This is super convenient and takes up little space. Installation is simple and straightforward but if you’re not experienced with audio installations seek assistance from someone knowledgeable. It is backlit for easy operation in any lighting conditions and it’s waterproof. The Bluetooth connects flawlessly and works great. I definitely recommend it. For the price it is a good value in my opinion.
