Is it possible to simply add on xm to an 03 that doesn't have it. It doesn't come factory with an antenna, but subsiquent to my initial hack to get dvds to play, it enabled two xm tuners when I scroll through the bands (adds xm1,xm2 to the am,fm1,fm2). Just wondering what it would take to get this done.
Thanks

Very easy, now, if you have the Black interior (late model year '03 and up). If you live in Florida, contact DanDan, and he'll put one in. Or if you're a DIY type, go to radios and more. They now have the CTS kit.

Make sure you tell them you have the Nav when you order. They have to add some wires to the harness for audible directions and voice commands pass-throughs. -1- and I both have done this. (mine doesn't work unfortunately, since I found out the early pewter interior is pre-XM option).

I am pretty sure that it is the late model. It is an '03, and it was actually a November of '02 manufacture date. I am also pretty sure that you could call me a do it yourself-er. I installed aftermarket equipment in all the high end cars for about two years. Was even certified for 99% of it. I just wanted to know that it could be done before I started ripping into it, being I am still covered under warranty. I would rather not void anything yet, but I really want my xm back.

:( Ody, That's bad news. Are you still having problems with your CD changer? If so, throw it in the trash and get a late model DVD NAV.

That's the plan (well, I may keep it to hack). I think upgrading to a DVD Nav is the way to go, for the XM and to fix my jammed CD. Specmo wanted $450 to fix the jammed CD, and I still won't have factory like XM. I'll swap the face plates to keep my pewter interior.

And I removed my XM Commander before I installed the XMGMD100 (which I fully intend to keep). doh!

:tisk: If Ody said it, it's gospel. The pewter face plates will be difficult to find.

Ody, what problems are you having with adding the xm? All navs should have the xm option, I have not seen one yet that was not. I posted on the srx section how to install the xm option. Maybe I can help. I had my first cts I could not do xm on. It was a 03 with the bose non nav radio. Radio said it was made in germany. When I tried to program it with the tech 2 it would not give me the option of activating the DRR module. According to my schematics it should work but found out he had the radio changed 3 times already under warranty, so no telling what radio is in there. The radio had the six disc changer too. I had tried everything nothing short of taking a hammer to it! If you have nav the radio should already be programmed and it is only six wires. Like I said I finally posted how to install it in one of my posts on the SRX forum. ODY, if you want to call me and I will try to figure out the problem, you can call me during the day at 954-520-2499. If I don't answer just leave me a message and I will return the call. I have a cd changer to put in a CTS in the morning then I am off to put in Power Windows and Locks in a new Caravan. Friday I have a STS I have a NAV radio conversion. Should be interesting since I have not done one yet. Even though I don't recommend anyone short of a professional installing the xm option through the hard wire route it is only six wires and as long as you are careful it will save you money. Hopefully I can one day take the digital camera and do a step by step pictorial to make it easier. You will not void the warranty as long as you do not mess up the install. Thats why I recommend having it professionally installed.

I had the same issue. I used the radios and more harness to make sure everything works, before I splice my own 6-wire harness into the factory harness. I don't like the stiff wire and bulky connectors of the kit. It makes the install easy, but is overkill for installing six wires. I've figured out the pinouts, the Molex connector and terminal part numbers, and which wires that will need to be spliced (power, ground, and Class-2 serial bus). The three audio wires plug right into empty sockets on the C3 connector.

The regular six disk changer non-nav DIC head unit is made by VDO in Germany. I'm not sure where Delphi builds the Nav systems.

The issue for me was that the Tech-2 programmer didn't find the 'digital radio receiver (DRR)' option to enable. The mechanic is a buddy of mine, and he spent two hours working on this, with me next to him, at the GM dealership. He did flash new engine calibration software (45 minutes to download from the Tech-2), among other firmware updates. If the XM firmware isn't already in the radio, it simply won't work, since the Tech-2 only activates that option. I've been told that you must send your radio back (or exhange it) to Delphi for any software fixes, like the XM low volume levels fix.

When I looked up the 2003 RPO Order Guide over at CadillacFAQ, it shows XM as not available until mid-02, when the switch to the black interior and the DVD Nav. If the non-nav you were having problems with was in an early '03 with the pewter colored interior, I'm sure this was the issue. Mine is a very early model (2/02 build date) with the pewter dash and CD Nav. I would rather upgrade to the DVD Nav than put my XM Commander back in (which uses the same XM Direct tuner).

Have you had previous success with the CD (Pewter) Nav or non-nav and XM install?

full xm kit at xmforcadillac.com (radiosandmore.com)...

You need to have an XM ready radio for it to work (as mentioned above).

The programming instructions are in the docuement library on the FAQ (print them and take them to the dealer).

Ody, I did not know you have the cd based Nav? The unit I had was a made in Germany product. I had the same problem programming the radio. No option was given for the DRR. We even took the tech 2 and put in 2004 and the option came up. But as soon as we went to save it, the tech 2 said communication failure. We are going to take a stock unit off the lot and switch the radio and get him his xm. The guy is the Vogue Tyre (Yes, that is the correct spelling) manager and has been using a Delphi for a couple of years. He watches me put in these XM's in all the time, and I cannot get his to work. His build date was 3/03. But I think he got a older radio. He has the black dash too. I am looking to see if we can get a firmware upgrade. I have a friend on the inside looking into it.

Let me know if Delphi will do firmware upgrades. I'm having a bear of a time getting to anyone knowledgable. All I get is "Cadillac radios are not upgradable or interchangable", and "You can't do that . . . it won't work", to which my reply was " I can, I did, and it worked, but that's not the issue . . . can you fix the XM!"

I'll gladly send my Nav back in to get the jammed CD player fixed and a firmware upgrade for the XM, if they offer it. Otherwise, I'm upgrading to a later DVD Nav, and swapping my faceplate.

odysseus,
Do you happen to know the part number of your cd nav? I'm wondering how much it is on gmpartsdirect.

I've been meaning to photograph or write down the PN during the many times I've removed it, but I haven't. I've typed in several part numbers for Nav's listed on EBay into GMPD, with nothing coming up. They may only be able to get the most current ones, with older ones only exchanged through Delphi. I got mine (Pewter, CDROM based) on EBay last year, and I've only seen one other since then, unfortunately.

I do recall someone posting a part number that did come up for a DVD Nav. It listed for around $3500, with the GMPD price of $2500. There was recently several brand new DVD based '06 CTS-V Navs on EBay, with a BIN of $2300.

Yeah I saw those, but the price :(
I'm not in a huge rush, I'm still in my information gathering phase :) I guess I will have to be patient and wait. Your idea of swapping a pewter faceplate sounds good, I wonder if thats something you could get through the dealer.
