Does VSS stand for vehicle speed sensor?

How do you connect the VSS to the GPS nav HU? I plan on trying this conversion myself.

Thanks

Cheers

So far no problems at all. But I understand the hesitation to buy with no way to return it. It was a big gamble for me, but now I'm glad I risked it!

I contacted GMPartsDirect about my NAV DVD order today, and they replied that my Dec 30 order didn't get processed until Jan 1. I find it hard to believe anything happened on the 1st, but that is what they said.

Klaus, I spoke with my dealer this afternoon and he can get me one for $1650.00 including tax and shipping. However he told me the unit is not returnable because GM told him it would not work. I told him to give me a few days, I was going to wait to see how your's worked when you got your Disc. However for the most part if I just use for the Radio & Cd player I should be fine. Have yoo had any problems with it so far?

you won't be able to use your DVD to plat movies for the kids. What this does is lets you connect another video sorce to the HU and see it on your screen. To me it is lame.

Thanks Phil. I have to admit - It was a very expensive experiment, considering how GM, Hummer, and Delphi said it couldn't be done!

Fortunately, I'm a rebel that doesn't like to be told something cannot be done.

Is that the part number listed after the items? Also do those guys take Credit Cards? I want to do this and I think it would be a great mod to do. How long did it take to get the unit from these guys in CA?

[Klaus]

Well guys, I got my DVD NAV disc, and I have some bad news... You're going to want to spend some money!

Jim,

I ordered it from GMPartsDirect on Dec 30. I should get it some time this week.

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.

I jus t bought the addon 6 disk changer that going in the escolade and tring to find a XM box from a juck yard to do it. the problem is that it will lock up when installed in another truck. the docs I have says it has to be replaced if that happens because the dealer are not able to unlock the xm boxes.
not sure if they will do a warrenty exchange on it or not if that is what happens.
I am going to find out one of these days.

Klaus,
Any news on the VSS connection. I would also be interested in your overall impression of the system to date. Give me a shout if you ever need someone to wheel with!

Have you connected the VSS yet?<HR></BLOCKQUOTE>

Not yet... I'm working on getting another music source to connect at the same time I connect the VSS.

Also, it has been too COLD for me to work on the truck.

Bevo,

I just tried a DVD movie to be sure. It will NOT play DVD movies. It gives an error about not being able to read the data on the map DVD.

Sorry, but I didn't think GM's lawyers would allow a movie to be displayed where the driver could see it.

I looked in the service manual but I could not find any part number for the amp. Where else should I look?

Cheers

Thanks Klaus
I could have used that last week before I spent 17 bucks for the cadi nav book. I will check out the PIE before I buy.
Thanks
