[@randygregory7826]

So question. If I use the Joybring you are showing with reverse camera, etc anc 3wXv4V5 adaper harness I will maintain my steering wheel volume controls and the chime system.? I would like a unit with Navigation, also. When you check on the Boss system they want to know your RPO code so they know which harness to use. Any Idea on which RPO code they are looking for. the label in my glove box does not identify which code is for the bose system I already have. all this gets very confusing. thanks for you video and help. Reply I posted 2 comments, not sure why you didn't see them. Sorry about seeming to be complaining, I figured the above system won't give me Navagation without using a cell phone, So I need to look for something else. Sorry to have been a bother. Good job on your videos. My car is a 04 envoy, but pretty much the same. Thanks again, Randy

[@southcreekoutfitters]

you guys do great work. Really enjoy my blazer now that you put the Apple CarPlay in it.

[@johnnyrotit844]

Direct to the point, very informative. Thank you. I truly wish you could make a video with one that has the premium system with the rear seat controls and how to be able to retain those or do a cool mod with that part as well.

Thanks for the video. :D The step by step process of not only removing the old radio but installing the new one was terrific.

Good video and well explained. Unfortunately i am building (soldering and heatshrinking) my harness and the whole reason i watched this video was for the illumination wire. I was really hoping for something to the effect of.. "If you have a none bose gps factory unit the pin you need is this one top or bottom row 4th from the left Ex. check for continuity from the pin to the wire to ensure you have the correct one and solder it up." not a huge deal i will figure it out when i put it in. Also i will let you know i didn't connect my power antenna wire to my remote so i will let you know how that plays out. might have to solder that connection anyways. As i don't have a power antenna it seems redundant. Haven't checked the wiring diagram to see what other vehicle systems that powers though..

[@randygregory7826]

Ps really just trying to get something with backup camera, navagaion, and maybe android bluetooth. Don't need amp or sub woofers etc. Mainly a backup camera that is on the radion, not some extra unit. So thanks for your help. hope things are well in Provo. Randy

Thanks for the reply. I have put in many aftermarket radios, but theses days with the chime system and onstar (which I don't use), trying to find a unit and all the extra things to install it can be a pain. So you say the Boss system would be good?

What type of wire harness and chime retention unit would I need for a 2008 Chevy Trailblazer LT with the Bose stereo? I've had no luck even after spending a ton of money on several that were supposed to work with the Bose factory stereo with the Bose Digital Amp. I'm trying to swap out the factory stereo because mine is none functional ive tested another Bose stereo and there's power going to it but a touch screen with modern features would be great. Thanks for any help you may be able to provide.

My radio has an illumination wire. Can I just connect both orange wires to it?

[@nickjackson4683]

I wired in a head unit on my 2008 trailblazer, followed all of the instructions and double checked my work, however I was unable to find which wire was my ignition signal. I wired red to red and yellow to yellow as my harness instructed but my radio doesn’t cut off with ignition, i have to manually power it off at the unit itself. Am I missing something? I used the same metra harness shown in the video, I even tested all the leads at the factory connector for power when cycling the ignition. Just curious which wire in the connector was supposed to give me ignition?

Hi, It is a standard 2DIN size radio?

[@nathandonahue2965]

I used the exact same products as you, but mine did not have the interface illumination tab on it, just curious if you remember what color it was or if you had to double up any wires

[@ProvoBeastAudio]

Sure, if none of the illumination wires pass through the harness resulting for the need to use the interface illumination wire, it doesn't hurt anything just to connect all of them together. Alternatively, you can use a multi meter or continuity tester to identify which wire you need and eliminate the ones you dont.

[@seattleboatdetailingmobile1926]

Awesome video. I heard the mileage info may be stored in factory radio.. on. The trail blazer is that a myth or true?

[@Wrkncacnter777]

False. Odometer value is stored in the EPROM on the cluster, it's the same with all GM trucks from this era. The odometer value might be written elsewhere, but if you put a junkyard cluster in a car it'll carry the donor vehicle's odometer value with it. jeffescortlx here on youtube has a number of videos where he repairs clusters, including pulling the EPROM values from a broken cluster and writing them to a donor cluster.

[@timburns9747]

I did this EXACT install, I do not have SWC or Bose, but I do have Onstar. For some reason the radio is shutting off every time I open the door, WITH THE ENGINE ON. I plugged in my OE radio to make sure it wasn’t my door switch, it stayed on. Any ideas?

[@deitrichgaddis5247]

Do you have to have the smart harness because when I hook my stereo up in the car I have no power but when I hook the stereo up to the battery the stereo comes on

I have a 2002 Bravada oldsmobile, even though it has Onstar system(Which is not activated and I do not require it) just as I would not mind not having the steering wheel controls, can I use the cheaper harness or do I require to use one that retains the steering wheel controls, also the speakers are not heard without the factory radio, with this harness will this be solved also?

[@gerardohtx207]

I’m wondering the same question… did you ever find out???

[@unfinishedquest]

You can use a cheaper harness that doesn't enable the features you want and it will still work, just won't be able to use the features because of course, you bought the harness that wouldn't let you use them.

[@derekdemorrow]

Will the LC-GMRC-01 HARNESS WORK IF I HAVE BOSE AND ONSTAR AND STEERING WHEEL CONTROLS? THE CONTROLS AND ONSTAR WILL JUST BE INACTIVE? OR DO I NEED THE HARNESS FOR THE BOSE AND ONSTAR AND STEERING TO MAKE THIS WORK SINCE MY CAR HAS THOSE FEATURES?

[@Wrkncacnter777]

No, with Bose you need the GMOS-04 smart module, and for steering wheel controls you need the ASWC-1 adapter.

Does the Smart Harness do anything to activate the Red wire for power? I purchased a harness and wired to spec with my Dual radio and the Red wire out of the harness is not giving power when the ignition is on.

[@ProvoBeastAudio]

Yes. Your GM vehicle doesn’t have an analog accessory red wire as the “turn on” wire is data controlled, and so it has to be generated by the smart harness for the radio. Be sure to get the right harness for your vehicle.
