Certain Honda Navigation radios have posed a problem when adding a CD Changer, Auxiliary input adapters or iPod interface to the factory system.
That is because on some radios, the navigation connector must be disconnected to make room for the aftermarket device.
In such circumstances, the GROM HON1-Y - adapter harness can be used in order to make the things work. 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 the HON1-Y cable, then connect the navigation and the aftermarket device male plugs in to the female connectors.
