If looking to stream from smartphone in 2003-12 GM car, truck or SUV, then all that is needed is a hideaway XM module (U2K) and/or RSE (DVD).

Press the radio "BAND" button to cycle through FM1, FM2, AM, XM1/XM2; if XM1/2 appears your vehicle supports our A2D-GM3x music streaming module, but if only AM/FM band is display or vehicle does not have RSE; this module, sadly will NOT work. The A2D-GM3x connects to the hideaway XM module usually behind glovebox (trunks, SUV's etc.) or trunk (sedans) and allows users to pair smart device and stream internet music services, turn-by-turn directions, audio books and more on the car audio system. When in the mood for XM (if subscribed) or RSE (DVD); simply un-pair or disable Bluetooth on smart device and enjoy XM lineup or DVD audio as customary. Note: Disabling Bluetooth on smart device is only required to hear DVD audio on the car speakers, otherwise DVD audio will always play on headsets.
This module does not support hands-free calls (See our A2DIY-GM3x) but will mute streaming applications (e.g. music, navigation guidance etc.) when making /receiving call and resume play once call has ended. This clean solution leaves no wires or clutter on or around the dash and is a welcome addition for GM owners with RSE and/or XM module (with or without subscription). If subscribed, select subscribed from option in drop-down and XM service will remain uninterrupted.
» Supports 44.1kHz ADC, 96kHz DAC music streaming. Not for hands-free calls
» Bluetooth 3.0 (Expired XM subscription) or Bluetooth 5.0 (Active XM subscription)
» Quick and easy connection to XM module in less then 20 minutes (Headunit/radio removal not required)

» Auto-pair/un-pair upon entering/exiting vehicle.
» Enjoy Apple music, Pandora, Spotify, turn-by-turn directions and more
