2006 Trailblazer Ss After Market Stereo Install Guide Options

[Brain]

Seems a lot of people are afraid to remove their factory stereo from their vehicles these days. Dealer giving you crap about it being the brain of the vehicle, horror stories of people setting off thier air bags, GM data bus problems, etc... Heck, even Crutchfield says you can't mount a double DIN stereo in a Trailblazer, but then again, Crutchfield doesn't sell all these parts! Anyways, here is what you will need to mount an after-market stereo in your 2006 Trailblazer SS:

Step 1 - Vehicle Stereo Harness Adaptor:

Trailblazer SS with Bose & Onstar. This device will retain Onstar functionality and work with Bose amplifier system built into vehicle.

Remember to eject any CD's from your factory stereo and disconnect your car battery prior to removing your factory stereo. Buy a pack of butt crimps (look like little plastic tubes) from your local hardware store such as Lowes for wiring up your stereo harness to the vehicle harness adaptor. Follow the chart included with the vehicle harness adaptor/stereo manual for connecting the wires up. Disregard the portion that claims the Bose system cannot fade from front to back (it works just fine) just wire up the rear speakers like normal.

Factory XM tuner is located behind glove box, access from passenger side panel above floormats.

Excellent information! And very thorough. Thanks for sharing!

What do you think of that HU? I've been eyeing one ever since I first installed my CDA-9856 with XM direct and the high speed iPod cable. They're just a little out of my price range at the moment

Well, I came from an Alpine CDA-9835 and was dissapointed by the Alpine IVA-W200 limited tuning abilities (bass, treble, and what's equivalent to bass boost). However, simplifying was probably a relief as the CDA-9835 had so many tuning options, it was always difficult to get everything I listened to to sound right. Apparently now Alpine is making the decks simpler because you have to buy a seperate external sound processor, ie for Dolby decoding, etc... but when they are attached, they are fully controllable via the head unit like any other EQ.

My main motivation for sticking with Alpine was because I have a Sirius Alpine tuner with a lifetime activation on it.

At the time I bought it, Pioneer had one double DIN on the market which wasn't getting the best of reviews. Now they have another out but it's around $2500 with NAV included. Also, Kenwood was just coming out with their double DIN. With Alpine everything is alacarte so you can Nav later, etc... which is what I opted for since I already know how to get to Wendy's. My Trailblazer SS isn't exactly a road trip vehicle anyway, since it's gas mileage is so low.

Hi there,

I'm new here and also an active member of z71Tahoe-Suburban.com as 06TahoeZ, hence my username. I'm in the market for a TBSS and want to install my Kenwood gear (KVT911DVD, NAV, Satellite etc) in the new ride. Has anyone here done this install with a single DIN system.

I really want the TBSS but don't want to sacrifice my stereo equipment in my BMW. It took me years to get what I have now and I absolutely love the setup. Any help, advise or comments are welcome...

Great write-up Brain, top notch....

A single-din shouldn't be too difficult -- I assume the only issue you're going to have is fitting other adapters behind the dash; and I velcroed most of the ones on my setup to the bottom of the HU.

Also you may want to factor in the sizes of any speakers you may have. If the door openings are a different size, you may have to fabricate some brackets to bolt everything up.

[06tahoez]

What size are the speakers? Do you know?

I've got Boston Acoustic 5.5 Pro's and RX67's that I'll be yanking from my Bimmer before I get rid of it.

I think they're 6.5" in both front and rear doors, 3.5" in the dash, and 1" tweeters also in the front doors.

Sorry so will the Xm antenna control my pioneer sirius adapter?

Got nailed on that one myself... One of my wife's CDs is in the old unit, sitting in the garage...

Why would you not use the GMOS04 adapter from Metra instead? Does it not work? Says it retains On Star, chime and RAP functions and cost about half as much.

Is there any adaptor that will allow my XM reciever to work with a standard XM controll unit? I have a multimedia head unit with two RCA inputs and a single mini-din cable XM control connection to hook into an XM reciever.

I am sure there is some way to do it, would be nice since my XM three month still has a few months left on it right now.

great info

I am just curious on how hard it is to install the steering wheel controls!? I have the interface and I connected all the bose/onstar inface to the radio wires last night, and I am debating to do the sterring wheel controls and it looked more difficult?! did you have a hard time doing this?

[badass989]

Hey guys, I have a question for you about swapping the factory nav with an aftermarket unit. I have the Factory touchscreen, and I'm going to be swapping it out for a kenwood 8019 with bluetooth, nav, and a rear view camera. Also, I'll be installing new amps and speakers. What adapters will I need to get to keep the steering wheel, onstar, and rear seat controls? I've tried looking around but most of the adapters I find don't have very good descriptions of what exactly they do. Thanks in advance

Is this the right one GMAH24? I noticed above it has a B on the end, but I think this one is the one to use if you aren't keeping the bose amps?

For the steering wheel controls, I'm guessing I need PESWIAKJC?

Anything else?

Uh, do you guys read? I reference part numbers above for steering wheel controls and the proper wiring harness. The steering wheel interface is not difficult to install, be sure to splice and solder though, as I just crammed the wire in between the factory harness coupler and so every now and then the radio will change stations to the next preset on it's own. The PAC steering interface does not cut out factory buttons as it basically just taps the line and you program it to listen for certain buttons and then it interfaces those buttons to commands your stereo understands.
