Klaus can you update us on your progress with this install? I'm anxious....

Yeah, I know... Drty and I are racing to see how slow we can do our projects (his bumper and my XM install).

I plan to do the install some time next week, so I should have some good news for everyone then.

I bought the kit from gmpartsdirect.com. Everything installed with no problem.

It works properly through both the DVD/NAV system and the steering wheel controls. The song names and station names display on the NAV display and you get 12 presets on the radio, XM 1 and XM 2.

I used the XM antenna supplied with the kit and mounted it on the right side roof, symetrical with the Onstar antenna on the left side. Have seen it that way on other H2s. Had to pull down the headliner a little and drill 2 holes, but the antenna has a built in gasket that seals well on the flat surface. Total installation time was about 4 hours and it took me a while to figure out how to remove the sunvisor. Only modification to the kit i made was to cut off an extension on the reciever mounting bracket. All the other parts and connectors fit with no problem.

I just installed my XM Kit!

As BalanceMan said, works fine. More later...

Is there any reason to be concerned that the kit will not work with the 2004 6 disc CD Radio?

I bet it would work fine.

BalanceMan,
Exactly which part number(s) did you order? And exactly what was included in the kit?

Very nice picture Klaus. Looks great.

Drty,

I gave up on the idea of using the 2005 antenna, as the connectors are completely different. Therefore, I used the XM antenna in the GM Kit, drilling 5/8" and 3/16" holes in the roof to mount the antenna.

From GMPartsDirect:

GM PART # 12498768
CATEGORY: All
PACK QTY: 1 CORE CHARGE: $0.00
GM LIST: $397.14
OUR PRICE: $333.60
DESCRIPTION: Add on XM player for 2003-2004 trucks

Installing the antenna in the kit on 2003s with sunroofs may be a problem. 2004s and later should be a piece of cake, as the XM antenna can be installed where the AM/FM antenna is installed on the 2003s. The problem is with the reinforcing areas on the underside of the roof. It limits where the kit's antenna can be mounted. However, the antenna connector on the XM Tuner Module is standard, so a small stick-on aftermarket antenna could be used.

I took a bunch of pictures, and will work on an install doc in the next day or two.

Here are scans of the GM XM Kit's instructions.

Is it absolutely necessary to drill holes in the roof?

If you want to install the GM antenna - Yes. However, I believe you could use an aftermarket magnetic/stick-on antenna instead. I have not tested it, but I suspect you would just have to change the "sleeve" of the connector on the aftermarket antenna to plug it into the XM tuner.

klaus,

I am wanting to do this to my 2003 asap can you please provide the part #'s used for this install of the 2004 Navigation Radio and the GM add on xm radio kit?

Partsguy,
on the 2 above what type of price can you give compared to gmpartsdirect.

Thanks Ron

Ron,

Stand by on your NAV install - I will have further news in a week or so... I just ordered a Touch-Screen (TNR) NAV unit.

Klaus,

I am absolutely delighted to report that the kit works perfectly in a 2004 H2 with the 6 disc CD radio. Everything works and looks just like the one from the factory that came in my wife's '03 Tahoe. The antenna is permanently mounted where the am/fm radio antenna was on the '03 H2s. The only issue was the bracket, which was for a pickup. The dealer put it in and I have not had a chance to see how they attached the XM receiver behind the glove box.

I'm glad your install went well.

The bracket worked fine in my 03. The only thing I did was to remove the captive nuts from the bracket and slide some flat captive nuts on the dash support behind the glove box. That way, I could install the bracket with the XM Tuner already snapped in.

The only problem I see with the antenna is the 03s with a sunroof.

Hey Klaus:

I thought the story of the XM Radio install was over for me, but there is a confusing wrinkle after all. The radio has taken to shutting off from time to time. It completely shuts down -- even the lights on the radio controls go off. It then comes back on in about a minute. The clock resets to 12:00 when it does this. I presume this means all power to the radio unit is cut being cut off and then reestablished.

This morning, on a 1 1/2 hour ride, it shut off twice in the first 10 minutes of the trip, reset twice and then operated fine until I parked. When I got done with business, I started the truck and made a call using On Star before turning the radio on and the radio knobs again went out, as did the clock. After about a minute, the whole thing came back on and the person I had been talking to was still on the phone. Once I was finished with the call, I turned on the radio, set the program to XM, reset the clock and drove about 1 1/2 hours without further problems.

It is almost as if a circuit breaker is getting hot, opening and shutting everything down, and then closing again after a little cooling.

Do you have in your collection of service bulletins anything that might explain my mysterious radio condition? It was not doing this before the XM install, so I suspect it has something to do with that.

I suspect the 24 pin connector plugged into the back of the radio. If you read the instructions, what you are basically doing is removing the positive and negative wiring from the connector, then adding the replacement positive and negative wiring from the kit, which is essentially a set of "Y" adapters to give the XM tuner power. One of the pins could be loose or bent.

The only other thing I can think of is a loose or broken fuse.

Make the dealer fix it. You paid them to install it, right?

I did pay them to install it, and they are going to get an opportunity to fix the problem.

Nevertheless, my idea was that a little research on what the problem might be would save me some time. More often than not, with quirky stuff like this, previous vehicles have been returned to me at the end of the day with an invoice marked "could not duplicate problem." I was hoping to point them in the right direction before leaving it there.

Mysterious shutting-off of the radio problem solved. Work Order reports: "Found poor connection at terminal 1044 terminal loose. R & R radio and tightened terminal 1044 orange wire."

I kind of wish they had done that the first time if paid them to install the XM radio.

The XM radio was not the problem.

Glad they got it fixed for you.
