This cable allowed me to connect an aftermarket antenna to the stock head unit (Bose) on my 04 g35 coupe. The original antenna was dying and getting spotty reception and thus needed to go. The HU itself is a pain to get to in my car, but the cable is fairly easy to install; you just unplug the old one and patch this one in and plug in a new antenna. Once everything was back in place, my radio was back to life, no hiccups so far, for about a month.
