Compatible Nissan antenna adapter

The Clarion 40NI12 connects an aftermarket radio to the original antenna in 2007-up Nissan vehicles. It provides a direct link without cutting or splicing the factory wiring. Installers can retain the OE antenna signal when replacing the head unit.

Simple installation and passive operation

The adapter requires no external power and adds no active circuitry to the signal path. It sits inline between the factory antenna lead and the new receiver, introducing negligible insertion loss. No additional wiring or grounding is needed for normal use.

Questions about this item

How do I install the 40NI12 adapter between the factory antenna plug and the aftermarket radio?

Plug the adapter into the vehicle's OE antenna connector first, then connect the aftermarket radio's antenna lead to the adapter — reversing this order leaves the antenna disconnected.

Will the 40NI12 adapter need replacement if the antenna cable or radio is changed later?

The adapter is a passive connector; it only needs replacement if the housing cracks or the pins corrode, not when swapping cables or radios.
