The 9ft ÃDockÃn PlayÃ cable from iBOLT triggers ÃDockModeÃ in any Samsung Galaxy S4, S3, S2 or Note II. When DockMode is activated under ÃSettings-AccessoryÃ the sound from any application (not phone calls, only app sound!) will go out through the microUSB connection, allowing the user to connect the 3.5 mm aux-out connection to any car or home stereo that features a female 3.5 standard ÃiPod/aux-inÃ jack. By downloading and installing the iBOLT DockÃn Drive application from the Google Play store the phone can also be set to turn on/off Bluetooth and WiFi automatically when the cable ÃDockÃn PlayÃ cable is inserted, highly useful for both home and car use. Currently the following Android Ãdock applicationsÃ are compatible and can be set as Ãdefault appÃ to start with the iBOLT Plug & Play cable; iBOLT DockÃn Drive, TuneIn Radio, Slacker Radio, CarHome Ultra and Ulysse Speedometer. The 9ft cord is long enough to allow the user to place the handset on the left side of the steering wheel if used with a car holder in the vehicle. Or, slide the phone into a bag and connect to a boom-box for playing streaming music from the phone when on the beach, boat, camping etc. A great application is also to connect to home surround sound system and play music For charging the phone battery the USB plug must be connected to a standard wall charger if used in the home-environment or to a car charger or USB port if used in a car. iBOLT recommends to always keep volume at ÃmaxÃ on the phone and regulate volume on the stereo for optimal sound quality.
