My wife has told me I am obsessed with getting satellite in "her" car, so this will be my last post on this subject. I have all but given up getting XM installed to work through the Nav system. From what I have read on here and other places on the web, it would appear that I can get Sirius installed and have it work through the nav system. Just wanted to know if I am correct in my assumption that I can get Sirius installed in an SRX that has the Bose with Navigation, but no factory XM installed and have it work through the Nav head unit.

Thanks,

Tom

Is that a yes?

I've been trying to get this information since June. I am in the same boat as you. From all the searches that I have done, it is possible but you have to add pins behind the radio in order to use the stock cabling. I wish I could be of help, but I don't know what needs to be done. If you are in South Florida, go see DanDan.

It definitely can be done... I did it. complete upgrade from non-bose, non-nav radio, no xm to bose, nav radio and oem xm. check my other posts on the subject.....

Since my upgrade, I believe I saw ewill or someone say the xm modules are now off parts restriction, so you might check with your dealer or GM Parts Direct for ordering....

Let's see if I can remember in general.... there is a splice pack in the right rear quarter panel (white 20 something pin bus type connector wrapped in black tape that takes specific Yazaki terminals. You'll find brown (audio), green (audio), white (audio-ground) purple(lan) grouped by color for bus terminal connection. Your connector for the oem XM connector which you can order from GM or Parts Direct would have these connections coming from the splice pack, so you'll have to make them yourself. The nav radio may already be wired for them if for example you also have the rear dvd player. you'll only need to splice into the splice pack. If you don't have the dvd you'll have to check the pinout and circuit to see if the wiring is already in place all the way back to the splice pack. Also, power and ground come from another source. I chose to run it all the ways back to the OEM source which is the left rear fuse box below the second row seats. You could I think simply choose another power (accessory or hot all the time) and ground source as long as it doesn't introduce any ground-loop hum into the system.

I'm still looking for my notes and a way to scan them in.... hopes that helps... let me know how far you have gotten..

IF you read my posts on the subject, what I have learned is most often if it didn't come from the factory equipped with the options you want very likely the pre-wiring is not there... and you have to do it yourself.

Just to make sure I get this right, I have an 04 on the way with NAV, RSE, Bose no XM.

Since I have RSE I just need to tap the 3 audio wires and the Class II and Im good right?

If this is the case can I not just use the T harness from the kit and do it behind the radio?


Thanks Matt

Yes you could, but there is not a lot of room back there behind the nav unit. There is also a bare drain wire that should be connected, but that drain wire is also behind the nav unit wrapped in black tape.

You'll just have to know the circuits and the pinouts for the connectors. You are looking for left and right low level audio wires, not speaker output wires. If I recall it's the Green/w/white stripe(common), tan/w/white stripe(left), brown/w/white stripe (right). And the lan class 2 wire is purple, there are actually two class 2 wires but three purple wires....be careful, the third purple wire that is not class 2 wire, but something else. Let me review my notes tonight and I will let you know.

As a reminder, the nav unit will also have to be told to activate the XM bands by a tech 2 scanner. If you make successful connections and the xm band does not automatically show up, you'll need a GM tech II scanner to activate the DRR (digital radio receiver).

Sweet, this is good.

I was sort of in the same boat as you with converstions, the LUX/NAV upgrade in the trucks is lots of wiring but this will only be like 4 wires :)

I just had a lot of help doing it, so in retrospect I think I could do it again in an hour. Its a little difficult, but I took plenty of pictures and had a lot of coaching from another member in the fourm. But yes, if you have the NAV and the rear-seat entertainment system you will be able to add the Sirius or XM without having to add the extra pin behind the radio. You will be connecting, right, left, audio-common, data, power, and ground. I didn't even have to have the GM Tech turn it on. My NAV unit found the Sirius GM-SIR1 unit as soon as there was power.

Yaemish, can you send me more documentation on how you installed the SRX? I am contemplating doing it and I wish I didn't have to get behind the nav to do it (would love to have someone else do it). My email is tomduder@verizon.net. Thanks!

Here here! I am interested in adding sirus to my 04 with nav. No RSE though. Help me please. ucyiwork@cox.net if you can help me out on this.
