About the Axxess AXDI-GM3 Wiring Interface

Bob Bihlmayer

If you're planning to replace the radio in your 1996-2005 Cadillac, the AXDI-GM3 wiring interface from Axxess will retain your warning chimes, 12-volt accessory power, and retained accessory power (R.A.P). The module also provides the outputs (parking brake, reverse, speed sense) you'll need to install a navigation receiver. The interface has a built-in speaker to produce all warning chimes. The AXDI-GM3 works with non-amplified systems or when you're bypassing an amplified system. Does not retain OnStar®. Warranty: 1 year.

  • Radio replacement interface module

Product Research


Vehicle Compatibility: The Axxess Integrate AXDI-GM3 lets you replace the factory radio in select 1996-2005 Cadillac vehicles with an aftermarket head unit, while retaining certain factory features.

CADILLAC Catera 1997-2001
Deville 1996-2005
Eldorado 1996-2002
Seville 1996-2004

Notes: You must bypass the factory amp in the following vehicles to use this interface.

  • 2000-2005 Deville
  • 1998-2004 Seville

Retained Factory Features: The Axxess Integrate AXDI-GM3 radio replacement interface retains the following factory features in your vehicle after you have replaced the stock radio with an aftermarket head unit.

  • RAP (Retained Accessory Power): The AXDI-GM3 is compatible with your vehicle's RAP (Retained Accessory Power) feature, which keeps the radio on until one of the doors is opened.
  • Warning Chimes: The Axxess Integrate AXDI-GM3 will also retain all of your vehicle's factory warning chimes.

Notes: The following factory features are not retained.

  • OnStar
  • Amplifier
  • Steering Wheel Control

Outputs: The Axxess Integrate AXDI-GM3 provides a 12V/10A accessory output and navigation outputs to make installation easier and less time consuming.

  • 12V/10A Accessory Output: Since there is no 12V accessory wire in the vehicle's factory harness, the AXDI-GM3 is designed to provide a 12V/10A switched accessory output to your new aftermarket stereo, preventing you from having to run an accessory wire to the fuse box or underneath the steering column.
  • Navigation Outputs: The Axxess Integrate AXDI-GM3 provides navigation outputs (Parking Brake, VSS, and Reverse) to help ease the installation process of an aftermarket navigation stereo.
