Introduction
Many GM owners will be pleased to know they are now able to add Bluetooth
music streaming features without changing the original radio. The A2D-GM3
Bluetooth receiver works in select 2003-09 Class II Radios with External 6/
10 or 12-disc CD changer** and/or an XM Tuner module (with or without
subscription) or RSE (Rear Seat Entertainment)- vehicle must have at
least one factory option which remains connected and functional.
Note: The 6-disc changer built-into the AM/FM radio is internal not external or
remote.
A Bluetooth wireless connection means no wires, clutter or complicated setup.
