Fitting some audio devices such as MP3 and satellite radio to GL1500 Gold Wings can be difficult due to the lack of an auxiliary input, such as the GL1800, Ultra Classic, and Venture have as factory equipment. The Kennedy Technology Group Aux Retrofit Kit gives you a direct auxiliary input for use with all of the Kennedy audio accessories such as the IsoSet, AuxSwitchSet, CellSet MC/GPS3, and so forth. Note: This item is just the circuit board itself - more components will be needed to connect your audio devices to your Gold Wing, and a switch will need to be installed.
