Installing the 2004 GM DVD Navigation System in a 2003 Hummer H2

Installing the 2004 GM DVD Navigation System in a 2003 Hummer H2


Parts:

DVD Navigation Radio: 15204335 $1730.00
GPS Antenna: 15207447 $ 54.30
DVD Navigation Disc: 15105609 $ 220.13

TOTAL $2004.43



Summary:

Notice – I do not yet have a DVD Navigation Disc, so I cannot verify that the Navigation function is operational.

I installed a new unit purchased directly from a GM dealer. Other than needing to modify the GPS antenna bracket to mount it under the dash pad, this was a plug and play swap. No dealer programming was necessary!

Details

The connectors on the 6 CD changer radio are exactly the same as the NAV unit. The NAV unit has an additional plug for the GPS antenna that mounts in the dash.

Finding a dealer that could sell me the NAV unit was a real struggle. Every dealer that I called tried to enter the part number in their computer, and came up empty – Meaning that they could not order the part. Then I called a local GMC dealer. He also could not order the unit. However – He went one step further for me. He entered the part number in his national parts locator, a system dealers use to find where parts are in stock at other dealerships. A Cadillac dealer in California had 5 in stock.

I immediately called the dealership, Cadillac of Menlo Park, (650) 688-1543, and talked to Mike in parts. He said that they regularly swapped out the units in Escalades. All 5 units he had in stock were sold, so I had him order me a unit.

He called me when the unit shipped, and stated he ordered 12 more units. I don’t know how this dealership can get these units when no one else can – But they can get them.

I ordered the GPS antenna, and later the Disc from GMPartsDirect.com. I should have the Disc in the next few days.

The radio, CD player, OnStar, rear seat controls, and steering wheel controls all work perfectly. As I stated above, I cannot test the NAV function until my DVD disc arrives. However, I have no reason to believe there will be any problems.

I have taken 90 digital photos during my install, and will work on a write-up.

Just to let you guys know, with the help of Klaus' instion description, my 2003 H2 is now Nav-equiped!. No amp compatabilitiy problems at all.

[Klaus]

Congratulations, and welcome to the forum.

My next project is to add the 6 CD Changer from the Escalade in the OnStar location. I have most of the parts and instructions. Hopefully, in a couple of weeks I’ll have it done.

I also want XM Radio, so I’m working on that as well.

Shouldn't the unit you bought be able to play XM radio? I know the DVD NAV that is coming with my SUT has XM.

That's great news that your install worked. I've seen one for sale on Ebay so far and I think it went for $1550. I plan on selling mine once I get my SUT as it was preordered with the build. <HR></BLOCKQUOTE>

Unfortunately, the Factory XM Radio Option from GM includes a separate digital tuner box... And it is NOT available for sale. Also, they are VIN locked to the vehicle they are installed in, so a used part is not an option. The dealer cannot unlock them.

[Klaus]

I’d like to add that the Chevy Avalanche guys have a great forum, and have really taken the lead on electronic goodies for GM trucks.

If you get a chance, I highly recommend you take a look at their forum:

Ladies and Gentlemen,

Jason has added a link to the Navigation Installation Document on the "FAQ" page. Check out question 6 in the "For H2 Owners" section.

the part number is under the amp. I think it should be #15199992


I guess I will change the clown. I will put makeup on it for the next guy.

If you are interested in playing a DVD the GM nav system may play it when the H2 is park and the parking brake is on. Some other systems work this way.

Hope it all works out. I am happy with mine and I am sure you will like it. Just now if we can use it above 8mph.

Did you do the swap out yourself? How long did it take? I appreciate all the time and info you have given to this subject.

[Klaus]

I finished bolting it in on 01/02/2004.

It's interesting that you are looking at the changer and the XM box. That would be ideal. However, looking at the schematics of the Escalade, it appears that the add-on CD player and the XM box use the same pins on connector C2 of the radio. I could not find a schematic showing them connected at the same time. I wonder if it has to be one or the other?

I guess the easiest thing to do is wait for the Blitzsafe Skylink adapter for my XM. Blitzsafe says I should also be able to connect their soon to be released AUX adapter along with the Skylink adapter. I could then connect a digital player and have my entire music collection to choose from!

HappyJack,

I have no idea what Bose incompatibility that they are talking about. The audio sounds the same to me as it did with the 6-CD changer installed.

What can I say? Mine works. Yours may or may not work, and mine might burn up tomorrow - But so far, so good!

Klaus
when did you get yours done

[FrgMstr]

Excuse my ignorance, but what exactly is the "Rosen unit"? I did a search but came up empty handed. Thanks!

I did it in 2 leisurely days. Day 1 I used to disassemble the dash. Day 2 I went to Sears and bought metal sheers so I could modify the GPS antenna mount to bolt it to the dash of the Hummer. I then reassembled the H2, while taking pictures.

If you are in good with your dealer, see if they can find out if the GPS antenna made for the 2004 H2 can be purchased. I have not been able to get any info about it, so I bought the GPS antenna for what I think is the Escalade and modified the antenna mount.

I install a nav HU in my North Face Avalanche in Dec, Started on Nov. 24 when I got the HU from the dealer and GPS. Installed and everything worked but the audio. after a few week of research I found out that I needed a diffrent amp. The Avalanches come with a cheep Bose amp so I got the amp and rewired the conector for it only to find out it needed to be programed. Dec 24th got it Programed and whala sound. One thing the you need todo in the hummer is conect the VSS to the HU so it will work faster on the Nav. If you have ? about how, ask You will Like it more.
