Yes, I have an 03 CTS and was wondering were to buy a factory 04-05 radio with the satellite source already included. Is this possible or do I have buy the XM unit seperately. Thanks
Where to buy a factory radio w/XM?

There is an aftermarket solution for your car. Its true plug and play just like the factory. Oh, and the XM part ont he factory is separate from the radio (assuming the radio is XM ready). Oh, and you can't order the factory XM module anyway (it mounts on the rear deck of the car in case you were curious).
Go HERE. Those kits are PLUG ANG PLAY with our radios (specificy car type when you call) and will show song titles on the radio and be controlled as if it was from the factory (again, radio must be XM ready which I THINK all CTSs are).
I have not personally confirmed the above statement, but have assurances from different sources.
Tell 'em Reed sent you.

You can buy just the XM tuner and a Class-2 adapter from Radios and More. They have a specific kit for the CTS. -1- had worked with them to get it to work with the Nav system (they had to add wires for the audible directions and voice commands in the pass-through harness). When you call to order it, make sure you tell them if you have the Nav, if you want to preserve those functions. They have to add those wires for each Nav order. Since -1- was the first, and I was only the second person to ask for this, they have not increased the prices for that option, yet.

I ordered mine last night, and it should be Fedexed to me today. The kit is $299, with free shipping, and it works through your existing head unit, just like the factory XM tuner does.
I'm looking into how to adapt a less expensive version ($200) of the GM XM kit to the CTS, but I want to do the install this weekend to verify everything before I post it to the FAQ. Basically, I got the head unit pinouts for the factory digital (XM) tuner, and matched them to the XMDGM100 pinouts. It appears that all you need is to remove the appropriate wires and connector from the cheaper kit harness, crimp the appropriate terminals on, and plug them into your existing radio harness connectors.
It looks like it will work in theory, but I'll know better after this weekend.

If your existing radio is bose the software is in it already. You will have to program it though with the tech 2. I don't believe the base radio had xm software but do not quote me on that. I have one to do Monday at my dealership and will let you know if it works. Ody you are very smart and getting close. Too bad you spent $300 on that overpriced xm from United radio, but I know it's killing you to know how it works. I wish I could share more with you but this is how I make a living. I would like to know what you do for a living and whether you could understand why I am not willing to share much info? But your a smart person. Good Luck,

DanDan, I completely understand that since you do this for a living you don't want to share your corporate knowledge for free. I run a business too, and no-one can afford to work for free. I build spacecraft, UAV avionics, electronics, and test equipment for a living, so modifying cars is a hobby for me.
Decoding schematics and chasing down terminals and connectors is NOT very easy for the average person to do, and it's much more worth the $$$ to buy a completed system. Without ingenius folks like you, none of this would ever get off the ground. If everyone could do things like this on their own, there would be no aftermarket automotive sound system installation businesses. Even with the instructions posted, 99% of those reading them are going to realize that it's easier to pay someone to do it. Only a die hard electronics hobbyist would try it themself, even with a cookbook recipe.
Building a Class-2 data bus adapter for the XM Direct is not trivial. The labor alone will run much more than $300 for an engineer to design it, let alone parts in low quantites. Buying the XMDGM100, decoding schematics and building harnessing is much easier. It will still run close to $200, since no-one sells the XMDGM100 in anything but a kit with the XM Direct and harnessing. The first thing I did when I got mine tonight was crack open the case. It's a very nice quality board inside. It has no more than about $10 in parts, but they also need to recoup the non-recurring engineering costs to design the thing.
I've got a harness built, and the write-up almost complete. Yes, the kit I bought has a complete CTS harness for the Nav included, but I don't like all the adapters and extra wires. I want a clean factory looking install. I need to pull the Nav and do the actual install on Sunday to make sure it all works. There is likely already wires in the remote power or Class-2 locations on the stock harness, potentially requiring a splice. I'd prefer plug-n-play, but we'll see how it goes. I've got so many terminals left over from the Nav Phase-2 harness install . . . I've got to find a use for them somehow!

:tisk: He's not just an engineer, he's a SMART engineer. I'm glad he's on OUR team :worship: . By the way, the www.radiosandmore.com "factory" add-on XM radio for the CTS is EXCELLENT. Easy to install and works WONDERFUL.DanDan said:Ody,
Forget what you do for a living. I saw your profile. Engineer!!!!

Ody,
It is not as difficult as you think. What United Radio does is purchase the Terk kit from (Audiovox) who purchased Terk. What they did which I believe is very smart is they had the harness made by Flextronics. In other words they sub it out to another vendor. The key to doing the job is the GM serial interface adapter. In reality there are only six connections to be made. All GM's use the same Class 2 data. It is the wiring that is different. Since GM does not believe in one harness per platform vehicle. What that means if the vehicle does not have factory XM they use a different harness, and the wiring and plug will not be there for future upgrade. A mistake to me as that is potential profit for the company. Bad business decision to me. As a comparison Nissan uses one harness for that one vehicle allowing you to upgrade to a Factory Nissan XM or Sirius. It is actually is cheaper for them to do that as now they have only one part number and the cost is cheaper in the long run and they make money when the customer wants to upgrade. Most customers always want Factory first on there upgrades if the cost is reasonable. There will always be a place for the aftermarket as costs will always be much less expensive. When you purchased the CTS XM from United Radio they remove the harness that Terk gives you and replace it with there harness. The harness you get with the Terk harness is for the majority of GM radios. You need to modify that harness in order to save a few bucks. Now I am going to help you out a bit. There are only six connections you are going to need to have XM. All but one connection is on plug C-3 behind the radio.
RedWhite- 12volt constant- pin 7
Black- Ground- pin-8
pin-3-Audio common
pin-4-Right + Audio signal
pin-1-Left + Audio signal
This connector is grey and towards the bottom of the plugs, it is easy to tell as there is usually only 3 wires in it on a base radio. The purple wire pin-2 is for remote radio control supply voltage. Do not confuse that wire as serial data. Pin-5 is for export and listed as pink but I have never seen any wire in it. Don't worry about the shield as the Terk interface already supplies it.
Now you will still need a class 2 data line to finish up the install. That is on connector c-1. I use pin 8 which is next to the yellow part of the connector. But pin 11 is ok too. It does not matter which one as GM uses a star pattern system and it is a pass through wire. If the radio is removed anything after the radio is affected and will set codes to help the tech figure out what the problem is. Next you will need three wires for the audio as they are not in the connector. Since the connector is VW style all you have to do is purchase a wiring harness for an older VW factory radio. I use Metra products and the part number is not in front of me right now. I can post that later or edit my post. You will remove three of the pins with wires and install them into the factory connector. Not easy but not impossible either. The factory connector c-3 has a yellow insert that has to be removed in order to insert the wires. It Requires a small tool to remove it. Just remember to reinstall it after wiring it up. I highly recommend you solder all the wires for a permanent connection. I cannot emphasize that enough! I always solder my connections. After being in business for 20 years take my word for that. The most important thing that has to be done is programming the radio to accept the Digital Radio Receiver (DRR). This is one thing you will not be able to do yourself unless you have a Tech 2 scanner with the proper software in it. It takes me less than 2 minutes to do but the dealer will probably charge you an hour. It is worth it, they have bills too. Remember they are there to make money too. I also recommend having the radio programmed before installing the XM. It seems to recognize it quicker if it is done in that order. I have programmed the radio after the install and it takes a few times of cycling the ignition switch to get to work. If I program it first it works the first time. Now the people that have the Nav, of all the ones I have done no programming of the radio has been needed. I believe they already have been programmed. Now if you want to roll the dice and hopefully save the bucks you can install it and by some luck the radio you have will be programmed and save you some bucks.
ODY, if you want you can email me at strat[email protected] and I will give you pin outs for the gm interface. If you purchase the standard GM kit you will need the wire colors in order to interface it to the CTS. And if you want I can sell any of you daring enough to hardwire it and save money. The cost of the unit will be about $160 plus shipping. But I want to make one statement. I am providing this info for free and I want no liablility if you make a mistake and burn something up. I can't believe I am telling you this info but I am suppose to be mowing the lawn and it is raining out.
Now to make the post longer here is another bit of info on Class 2 data. The new protocol which has been out now for a awhile is the GM LAN system. The DTS is using it but I have not gotten my hands on one yet. The base DTS does not come with XM but all the ones I have seen are coming in with it. It will probably take the aftermarket a while to crack that one. All the 06 Caddy's are coming standard with XM so I am out of that market for new cars.:helpless:
Thats it folks as the sun is shining and the wife is taking my daughter to cheerleading for a game. Remember use this info at your own risk. :cool2: :cool2: :cool2:

:thepan: Dan, that's an unfair statement. The XM radio PRO up to a month ago, just happens to be located in one of the most out of the way, four corners in this country. You would have to move to the Keys to get any further away. Most of the people on this forum are do-it-yourselfers. Not cheap, just hands on. I asked you several times for help, sell a kit based on your information. You threw everyone a bone (tidbits of info) and then expected people to (flock) drive to south Florida. The guys at Radios and More couldn't have been nicer, or more helpful. Their $299 kit price is fair and includes no cost next day delivery. It's easy to install and it's "factory" looking. It would have cost me a minimum of three days driving, missed work, gas, lodging, and your cost for the PRO to have installed my XM. That's driving from Virginia. I got away with $299 and the self satisfaction of doing it myself. It was a simple install. Oh by the way, you think we're cheap, deal with the guys at YugoOwners.com!
The cheap remark was a joke. Did you not see the smiley faces? Sorry you took it the wrong way. I did not offer the harness as I have to hardwire it and as far as factory look, there is nothing to see. It's all behind the dash. I have no problem with United Radio's product, it's just expensive to what they are offering. At $299 you still need to program most radios. At $100 + and hour now at the dealer it gets quite expensive. Granted if you come to the dealership I do work at it will cost you too but they will back it up if you ever have a problem. Do it Yourselfers are on your own. I gave up and now you have the info.
