This antenna adapter lets you connect an aftermarket antenna cable to the factory radio in your Hyundai. The adapter has a standard female Motorola plug on one end and a male Hyundai antenna plug on the other.

You'll also need another Hyundai adapter if you are connecting an FM modulator with your factory radio. Warranty: 60 days.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.
