Need Radio wiring diagram 2004 chevy silverado 2500hd (oem plug)

Yea , and what is it you want to know ? Do You Need 2 DIN Car Stereo Did you buy an interface module ? PAC RP3 GM11 Radio Replacement Interface SWC for GMC Buick Chevy Onstar...

Hello Sandra Eldridge,

Your title says what kit you prefer... From what little I know about OnStar... "OnStar FMV" appears to be the (SMART) MIRROR
approach... My best recommendation would be to get YOUR
"FMV" from CRUTCHFIELD (see below)...

"PAIN-LESS AND WELL DONE"

I checked ontar.com and your car IS ON-STAR capable...

Sadly I always make things more complex than they need to be:
I don't think the LINCOLN "sound system" is inferior in ANY WAY... and think there has got to be a better solution than by-passing an already REALLY EXCELLENT human interface...
for a "SMART MIRROR" (FMV)... So BEFORE you choose THAT SOLUTION... I would ask you to find out WHAT SERVICES
are presently in your existing MIRROR.

CRUTTHFIELD technicians can do that for you... Phone them... Talk to them...

ELSE take it to your LINCOLN DEALER and ask what service THEY COULD equip in a new car... BECAUSE I can't park without my CAMERAS any more

(just kidding... never scuffed a tire!!).

Years ago CRUTCHFIELD offered a 3-SIXTY-3 solution for my NAVIGATOR... radio navigation system to integrate BLUETOOTH.
I was QUITE DELIGHTED to deal with their technical staff

I have felt the EXTRA SECURITY of knowing the VEHICLE is being tracked... (watched over)... and felt quite secure

I think onstar is a much safer choice than fumbling with your cell-phone trying to use siri while driving.

Hope it all works out well...

Sorry to pose another question while I'm supposed to be offering a solution.

You can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete

Not the Onstar. You have an amp in it that needs rewired. Color code for wires are so different. I use an ohm meter to fix the problem. Just a note. Onstar does't work after this.

My 2002 Chevrolet Malibu doesn have wiring harness
You'll be glad to know we do offer an OEM wiring interface from Metra for the 2002 Chevrolet Malibu. If the Chevy Malibu came equipped with Onstar, then here is the adapter you will need to replace the factory radio. If the Malibu did not come equipped with Onstar, then you will need this adapter instead. I hope that helps. Andy

The above link has the info on stereo adapters. They are expensive, but these adapters retain the original functions of the system.

It depends on WHICH PART of the OnStar system you want to know about....

> The control unit is located in the rear view mirror assembly

> The Vehicle Communication Interface Module (VCU or VIU) is located behind the rear seat back

> The Celular Telephone Module depends on whether your vehicle is equipped with GPS: With GPS it is located under the right side of the rear package shelf. Without GPS it is located behind the rear seat back.

it is possible to replace the radio in your car with a aftermarket unit using the following metra parts

Dashkit - 99-3301
wire harness - GMRC-04 non onstar interface
wire harness - GMRC-05 onstar interface
antenna adaptor - 40-gm12

It will fit, but the parts are expensive and it is not plug and play.

Parts needed:

Dash kit- Metra 99-3305 About $15-$20

Antenna adapter- Metra 40-CR10 (Chrysler antenna adapter) Yes GM uses Chrysler parts. About $10-$15

Wire harness/Interface- GMOS-LAN-01 (non bose or onstar) About $100
GMOS-LAN-02 (bose/onstar) About $120

The reason for the pricey harness is to retain data features on the vehicle and to interface with Onstar (GMOS02).

This is the right way so don't cut corners because it can cause issues on your brand new vehicle.

All of your safety chimes run through the stereo and not using the correct interface can cause issues with your gauges

www.metraonline.com or www.scosche.com are good sources for install parts info

sound like the head unit's out put mosfet is going bad, but i have also ran in to this problem when it was a speaker wires shorting out. so first check the connection on your rear speakers.

Smaller gauge orange wire is a dimmer wire. If the radio you are installing does not have a dimmer wire, just tape it up.

Hope this helps.

Rating appreciated.
