Add music streaming to GM Class-2 vehicles without compromising XM subscription.

Is your 2003-012 GM vehicle equipped with an XM tuner module? if YES, your vehicle is capable of supporting our A2D-GM3x music streaming adapter, however; if vehicle does not have XM tuner, purchase our BLU-GM3 instead. The A2D-GM3x module connects to the 16-pin connector at XM Tuner (does not fit radio connectors) to allow users to pair any A2DP capable device and stream from internet music services, turn-by-turn directions, audio books and more. When in the mood for XM (if subscribed) , simply un-pair Bluetooth device and enjoy XM subscription as customary. This clean solution leaves no wires or clutter on or around the dash and is a welcome addition for GM owners with XM Tuner module with or without subscription. (if subscribed, XM playback remains uninterrupted.)
