Introduction

Many GM owners will be pleased to know they are now able to connect our Bluetooth music streaming kit without changing the original radio. The A2D-GM3 Bluetooth add-on works on select 2003-09 GM Class-II audio systems that include an External 6/10 or 12-disc CD changer** and/or an XM module (with or without a subscription) or RSE (Rear Seat Entertainment)- vehicle must have at least one of the aforementioned factory options which remains connected and functional.

Note : Required external/remote CD changer is not the 6-CD changer built into some AM/FM radios.
A Bluetooth wireless connection means no wires, clutter or complicated setup. All user has to do is connect adapter (to radio), pair Smartphone or Tablet and enjoy GPS, Music, and other important applications on the car system.
See the Frequently Asked question at the end of this guide for details.

Installation –to radio

1.  Remove radio from the dashboard to gain access to connectors. (Vehicle specific radio removal instructions are not part of this guide, but available upon request)
