Introduction: Safety comes first when you re on the road, so having an intuitive and easy to use Bluetooth kit is essential to reducing driver distraction. The GM3x-HF kit is compatible with virtually all Bluetooth phones, and sounds great whether using it for mobile conversations, streaming music or listening to XM or CD Changer. In addition, a USB Charging port is included to keep your devices fully charged. One button with built-in mic conveniently installed on the dash is used to launch Voice Recognition application (Siri, Google Now, Blackberry Assistant etc.), initiate phone calls, launch applications and listen to XM. Thanks to the GM3x-HF Kit you can keep the radio,, retain XM or *External CD Changer while enjoying Bluetooth features only available on newer cars. Note: XM Subscription is not required but is retained if subscribed. Users not subscribed to XM are able to connect an auxiliary device to the module. Subscribers do not have this option. Users with External CD Changers: The Changer functionality is retained. See Frequently Asked question at the end of this guide for more details. Fig. 1 GM Class-II Radio plugs 2.

I m not the original owner and don t know if i f vehicle has XM Tuner. How can I find out without ripping it apart? Turn Radio ON. Press BAND button repeatedly to cycle through AM/FM/CD/XM1/XM2. If only AM/FM is displayed, your vehicle does not have the XM Tuner Module and therefore not compatible. 3. Does the GM3x-HF work on all Radios?

8. Will the stereo mute when I receive or make a phone call? This system will not mute audio playback unless radio is in XM mode (Bluetooth mode). If you are in Radio Mode (AM/FM) the radio will not mute and you must switch the radio to XM (Bluetooth Mode) 9. My second phone does not pair or find the Bluetooth Module?
