Good job Klaus!!!

Klaus,

Does it still work with your 6 CD changer?

Yes, it works fine. See picture 2 on page one of this thread.

BTW - I suspect this CD Changer will work in the H2:

Klaus how did you hook up xm? Do you have a GM tuner or an aftermarket one?

I used the factory GM XM Kit. PM your email address, and I'll send you my install doc.

Klaus,

Thanks - that is awesome.

By the way, I know you've mentioned it, but where did you put your OnStar with the CD changer in its place?

Also - one final challenge for you:

Get an iPod to work with this setup...even better if you can get it to somehow display the track name on the Nav (perhaps through a CD-changer interface or otherwise)...

You da man...

Hummer17,

I junked the OnStar. However, the easiest thing to do is to mount a different "magazine" type changer (like the one I posted the link to earier in this thread) somewhere in the truck (it comes with a 16ft cable). Then you would not have to do anything with your OnStar at all.

I have thought about a "Digital Music" connection. I wouldn't buy a specialized adapter to work with an iPod, or any other player. I don't want to get locked into a certain brand. Instead, I'd buy this adapter that gives you a standard RCA input:

SVG-707 General Motors Class-II Auxilary Input Adapter

I don't own, nor have I tested this adapter, but it is the one I would buy.

BTW - The same company that sells the AUX adapter also sells the magazine changer:

USASpec SCD-G7i 2002-Up GM 6-disc Changer

I had the second highest bid on Ebay for a 2005 TNR navigation radio and the six disc changer. This would be the same setup as Klaus.

The winning bidder didn't follow through and the seller has contacted me for me to buy at my bid amount, $1426

You can see the item here: http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5730917270

PM me with your email address and I will forward your email to the seller. I made other arrangements after the bidding closed and now don't need it.

Klaus- thanks for the email nice job. I am however confused as to which touch screen unit I can use in my 03 h2. It came with the factory in dash 6 disc Bose system. I seen this one- 05 hummer nav -and was wondering if this is the right one? I am getting the itch to make this mod but dont want to blow this much coin on something that might not work. Any help is appreciated.

If you have the Radio with Six-Disc CD, here's how to tell whether you have the Y91 LUX Amp, or the Non-Y91 Non-LUX Amp.

Press the AUTO EQ (Automatic Equalization) button.

If your choices include NORMAL, DRIVER, REAR, and SPACIOUS, you have the Y91, LUX Amp.

If your choices include CUSTOM or TALK, you have the Non-Y91, Non-LUX Amp.

Here are the TNR part numbers:

Y91 LUX - Part Number: 10377531

Non-Y91, Non-LUX - Part Number: 10377287


You must select the proper TNR for the Amp installed in your truck, or you will not get any audio. So far, all 2003s have the Y91, LUX Amp, 2004s may have either Amp (switchover during the model year), and 2005s have the Non-Y91, Non-LUX Amp. The Y91 LUX Amp communicates via the GM Class 2 Databus, while the Non-Y91, Non-LUX Amp does not. The LUX Amp has DSP.

Ok so I have the lux y91, if p/n 10377531 only works with y91 amps what vehicle might I find a used one from? Because if i am understanding this correctly no 05 Hummer has the y91 amp, right? And 04/03 hummers didnt have TNR monitors. Thanks again.

Correct. No 2003s came with Navigation, 2004s came with the INR (joystick) Navigation, and the 2005s come with the TNRs.

You should really insist on knowing the part number of the NAV unit in question.

It appears that Cadillac Escalades all have the LUX Amp. HOWEVER - Verify the part number before buying!
