About the Metra LC-GMRC-LAN-03 Wiring Interface

Problem: Installing an aftermarket receiver in many late model GM vehicles means losing the chime that warns the door is open, along with other audible safety warnings. You want to retain the chime and warnings, but you don't want to keep the factory amp or OnStar®.

Problem: Installing an aftermarket receiver in many late model GM vehicles means losing the chime that warns the door is open, along with other audible safety warnings. You want to retain the chime and warnings, but you don't want to keep the factory amp or OnStar®.

 Solution: Metra's LC-GMRC-LAN-03 GM Data Bus Interface lets you replace the factory receiver in these vehicles and keep all audible safety warnings, without having to spend the extra cash for an adapter that retains features that you aren't going to use.

Wire up the LC-GMRC-LAN-03 to your aftermarket radio, mount the module in a location where the chime can be heard, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. Warranty: 1 year.

Important Note: This LC-GMRC-LAN-03 interface allows you to keep your factory door chime (needed to keep audible safety warnings functioning) while providing a switched 12-volt power source for your new radio. If you do not use a compatible adapter when you replace your factory radio, you will disable the audible warning system in your vehicle. Crutchfield cannot provide a free wiring harness for your vehicle, and we strongly recommend that you use this interface when replacing this vehicle's factory radio. Failure to do so may result in serious injury or death.

Product Research

Features

Vehicle Compatibility: The Axxess Integrate LC-GMRC-LAN-03 is designed for use in select 2006-2012 GM vehicles with non-amplified factory systems (or when replacing the factory amplified system) and without OnStar.

Make Model Year
Chevy Cobalt 2007-2010
HHR 2006-2011
Malibu 2008-2012
Pontiac G5 2007-2009
G6 2009*
G6 2010
Solstice 2006-2009
Saturn Aura 2007-2009
Sky 2007-2009

*The 5th digit of the 2009 G6's VIN must be a J, K, or L.

Retained Features: The LC-GMRC-LAN-03 provides +12V/3A accessory output, retains warning chimes, and retains R.A.P. (retained accessory power).

  • +12V Accessory Output: In many GM vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The LC-GMRC-LAN-01 is designed to provide a 12V/3A switched accessory output (red wire).
  • Warning Chimes: The LC-GMRC-LAN-01 retains factory warning chimes through the use of an on-board speaker.
  • Retained Accessory Power (R.A.P.): The ignition power source of most GM vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The LC-GMRC-LAN-01 is designed to retain this feature.

Wiring Harnesses: The main interface wiring harness has a white 4-pin female connector on one end and a black 14-pin male connector (9-pins present) on the other end. The 4-pin connector plugs into the LC-GMRC-LAN-03 and the 14-pin connector interfaces with the existing factory plug. The harness also includes 9 bare wires that will need to be hardwired to your new aftermarket radio's harness. There is an second wiring harness (rear speaker harness) with a 16-pin male connector (6-pins present) on one end and six bare wires on other end. The 16-pin connector plugs into your vehicle's factory radio plug, while the bare wires hard wire to your new radio.

Q
what is the extra black box for? is it necissary for a new head unit to be installed?
[ Austin  Oct 01, 2020 ]
2 answers
A
It makes some of the vehicle sounds like the turn signal clicks
[ Benito  Oct 02, 2020 ]
A
Yes, it keeps the door chime when the door is open. Sometimes when install an aftermarket head unit, you lose the factory door chime.
[ Robert A.  Oct 01, 2020 ]
Q
Does this have a remote turn on wire to install an aftermarket subwoofer?
[ Garrett  Jun 28, 2020 ]
2 answers
A
There is a switched, 12-volt power wire for the radio to turn on and off with the vehicle but there is not an additional remote turn on for a subwoofer. That would typically be something you would add separately in an amp wiring kit along with power, ground, etc. You can connect with one of our friendly product advisors to put together a complete cart with everything you will need here: https://www.crutchfield.com/I-rET1c290/S-SUliZgSTXG7/support/ContactUs.aspx

If I remember correctly, yes. I have an amp and sub installed for my car. Just make sure everything is connected so it doesn't come loose.
[ James  Jul 13, 2020 ]
Q
Would i have to re wire a power source to make my new radio work?
[ kenard  Dec 26, 2017 ]
2 answers
A
No, this is a plug and play design. The only wires you need to solder will be the ones from the new deck harness, to this harness.
[ John  Dec 29, 2017 ]
A
The wire should go where the power source was wired originally. Referring to the crutch field memo/instructions that should come with the order if i'm not mistaken, but if not call crutch field's excellent experienced customer service. They will definitely know the answer!
[ Alex  Dec 26, 2017 ]
Q
Will this work with the premium stereo and allow the use of the factory subwoofer?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
