Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: The FM Direct Adapter is a hardwired FM adapter that allows you to feed the signal from the FM output jack on your satellite radio receiver into your car radio via the antenna connection, eliminating the outside static and interference you sometimes experience when using a wireless FM modulator. You also get to keep your local AM and FM stations when your device radio is turned off.
Note: This FM Direct Adapter is not a stand-alone FM
modulator and cannot connect to the headphone or audio output of
other external audio sources; it must connect to the 2.5mm FM output on a
compatible satellite radio receiver.
Connections: The FM adapter
box features the following connections:
- To Radio: Male Motorola
antenna plug on a 18" cable, plugs into the vehicle's AM/FM radio antenna
- To FM Antenna: Female
Motorola jack on the side of the switch box, accepts the vehicle's antenna
- Antenna: Male 2.5mm
mini-jack on a 21' cable, plugs into the FM Out modulated output on the car
Dimensions of FM adapter box:
Height = 1.25", Width = 1.875", Depth = 1.8125"
Installation: The FM adapter box is typically mounted behind the dash, near the radio. In this case it's
likely that no antenna extension cable will be needed.
Antenna Adapters: Some vehicles
(such as select GM vehicles, Volkswagens, Nissans, etc.) may require antenna
adapters in order to connect the FM adapter Box to your vehicle's OEM antenna
connectors. Please consult the Outfit My Car section of the Crutchfield website to see if OEM
antenna adapters are needed.
