Certain Honda navigation radios has posed a problem when adding a CD Changer, auxiliary input adapter or iPod interface to the factory system. This is because on some radios, the navigation connector must be disconnected to make room for the aftermarket device (such as Xcarlink)
This 2 Port-BUS cable will allow you to retain the factory navigation and connect an aftermarket interface. Simply disconnect the male navigation harness from the radio, and in it's place connect the male harness on then connect the navigation and the aftermarket device male plugs in to the female connectors.
It can also be used to retain your existing CD changer.
