Hummer H2 Radio Install, Keep OnStar, Steering Wheel Controls And Door Chime

[VegasMike]

So the first thing I did to my new to me H2 was to install my Kenwood Navigation until into the dash. Years ago I used to install car alarms and stereos, and even managed a few car stereo stores in So Cal. Needless to say I have tons of experience at doing this.

I wanted to create this thread to give out some links and so that there is a definitive spot telling web searchers what they need.

This is for a 2005 H2 that has the Bose system. I am installing a Kenwood DNX 6180 double din navigation unit.

So here are the products I used:

The finished install of a Kenwood unit:



Parts you will need:

I listed amazon links which will probably get you the lowest prices, but if you want to purchase the parts local, Best Buy should carry all those parts as well.

Dash disassembly instructions:

Pages 27-29

The GMOS-04 has an integrated plug to interface with the ASWC so no real additional wiring is needed. You plug the ASWC into the GMOS and it works. The ASWC is what will allow you to maintain your steering wheel controls and the GMOS will allow OnStar to still work through the new stereo.

The GMOS-04 also has integrated factory plugs, so you won't need to cut the factory harness to install this stereo.

The #99-2003 dash kit is pretty straight forward, it even allows for the use of the iso-mounting screws on the side of the radio you are installing.

Before you mount everything in the dash, test it all out including the sound level of the door chime, and OnStar. The door chime adjustment is a blue screw on the GMOS box, but the OnStar adjustment is a different process. You have to momentarily ground a wire while OnStar is making noise to set the level. The book for the GMOS explains the process very well.

The whole process took me about 3 hours. The toughest part will be disassembling the dash and the center console. Follow the guide on pages 27-29 of the link I posted and it will be pretty simple.

Also, there is not much room behind the radio in the dash, so you will need to tuck the GMOS and ASWC boxes either to the side, or below the radio.

If you are planning on adding an amp and woofer now, or at a later date, now is the time to at least run the remote turn on wire along with a set of rca's from the radio. I connected them and then ran them along the shift lever and left them coiled up under the center console storage box. So in the future when I go back to add the amp and sub, I only need to remove the storage box to get to the wires I need, instead of the whole dash again.

Any questions, please feel free to ask.

Wow that sounds great.
And so cheap too for the aux part (everything but the head unit)

I have a amp and sub hooked up to my stock bose system using a pac in line converter.

just wondering if you know any way to wire an adapter in to the stock head unit to allow my android phone to play music through the stereo?

Well, because you have an Android phone instead of an iPhone you probably already know that the number of options plummets, they simply make more stuff for the iPhone, especially when it comes to connectors since it has used the same plug for 5 years, and shares the same plug with every other iPod on the market.

But all is not lost! Check this interface out:

http://www.amazon.com/PAC-IS32-Modul.../dp/B004613FCE

It's an FM modulator that will basically take your direct audio signal and broadcast it thru an FM signal into your radio. You would tune to a certain FM frequency, and hear your audio.

Years ago FM modulators sucked, but they have come a long way and work pretty good.

Be aware that because GM decided long ago to use a smaller then standard antenna plug, you'll also need the following $10 worth of parts to make it work:

I could see this whole kit looking pretty good in a Hummer, instead of using the included mounting plate, mount the plugs in the wall of the center console storage.

like you, i had installed a Pioneer desk in my 03 H2 (and when i say I, i meant i paid someone else to install it)

you mentioned that for the steering controls all you need is the aswc adapter.
i forgot what i have installed, but i do have the onstar and door chimes.
my issue is, every single time i shut my H2 off, my radio will flip through all my presets until i open the door. this is caused from the steering adapter..

is this a common issue with the adapters, or is something fubar(most likely)

Mike,
Thanks for the info.
Do you know if there is one that would plug in.
I have tried many FM modulators only to find that at some point they all suck, so of course nothing beats a good ole fashion hard wire.
If i can hard wire it in, I would like to if you know anything out there

btw, you never mentioned about Vegas
My mother lives in Calico Ridge (Henderson on the Mountains edge)
My sister lives in Paradise (not on Paradise, in...). Basically it is Vegas but they just call it different now. Kinda like they did with Green Valley (which was originally Henderson)

To go hard wire you're going to need an "I" product, either an iPod or iPhone. Subscribe to woot.com, they have daily deals and have iPod touches from time to time at a good discount. In my H2 I have a 160gb iPod classic connected.

I'm on the border of Henderson and Vegas, about a block inside Vegas. The town area is called 'Paradise', so technically I live in Paradise!

Sounds like the programming on the steering wheel adapter may have gone haywire. As you know GM vehicles use the exit music feature that allows the radio to play for up to 10 minutes after the key is turned off and removed. The manufacturers of these adapters included that feature. It sounds like that part of the programming may have been corrupted.

The newer models are computer up-dateable, meaning they have a USB connection on them to allow the software on them to be updated. Depending on what is inside your install, it may just need to be reprogrammed or replaced. Either way someone is going to have to take it out and troubleshoot it.

It also may be as simple as just resetting the adapter as well, again though you would need to take the dash apart to get to it. You may want to take it back to the place that originally installed it.

thanks for the advice...

and i didnt say it, but great info in this thread.

i did my deck install a few years ago, but wish i had something liek this myself... might have done the install myself
