I own a 2005 E320 CDI with a COMAND control unit in the car. The unit has a satellite radio soft key. Does this mean the car is prewired for components to be added? If so, where can I get more information about adding satellite radio to the unit?

Thanks in advance for you help.

Re: Satellite radio

Yes, your car is prewired for Sirius Satellite Radio. All it needs is installation of the receiver, an antenna on the car's roof, and arranging for the service.

Your M-B dealer will do the installation, then you arrange with XM/Sirius for the service, which can be purchased one year at a time or forever, which is what I got when I had it put into the CL last year.

Contact your M-B dealer for the cost to do it, which seems to vary. It cost me $1,800.

The sound quality is slightly less than CD-quality and the sound cuts out briefly when you drive under bridges, since the line-of-sight between the satellite and your antenna is interrupted. But if you find even one station whose programming you like, it's worth the cost, and that's the key.

I would suggest that you investigate the programming issue first, by finding a channel you are interested in listening to. Listen to it for a while then decide.

When I did that, I found out that the channel I liked turned out to be not so good after all. But luckily I found another that's terrific.

Re: Satellite radio

I have installed an XM satillite receiver in my 2005E320CDI. Excellent results. No more that $200-300. Look and see if you have an input jack in the glove box.

Contact me if you want additional info on the installation.@

If you have useful information to offer on how to install a Satellite Radio simpler than the dealer does it, please share it with all of us.

Re: Satellite radio Addon

While I have an electronics backround I have had 3 XM satillite systems installed in MB's. i.e. 2001 E320,2005 SLK350 and my present 2005 E320CDI by independent professionals.
Basically you buy a converter @ your local outlet. (Best Buy ,Independent Car Electronics Installer). I have bought the XM "Roady".This is a converter that when installed will convert into either a vacant FM frequency or better yet can be input into an AUX. input,if available in the COMAND system. The main reason I purchased the ROADY was that it is very small. Small enough that in my E320 that I removed the ashtray insert and had the ROADY "hard wired" into the vehicle system. It is on whenever the audio is on. (or off as the case may be). The Roady is small enough that I can then close the ashtray cover over it. NO HANGING UNIT,WIRES ETC.
Best results,if possible, are obtained by going into the AUX input,which can be accessed from the COMAND audio screen. If not possible going through an FM conversion still provides very good quality. If going the fm route be sure to include a "direct antenna adapter"($30-40) for better reception.
On the SLK there is no ashtray position possible so had to make an outboard mounting.
Price for my Roady was about $50. Look for any model that fills YOUR vehicle requirements. Although I have always used XM I assume that a SIRIUS would work as well. Have never paid more that $150 for the installation.

IMPORTANT!!!! MAKE SURE THAT YOU HAVE THIS INSTALLATION DONE BY A TECHNICIAN WHO KNOWS WHAT HE IS DOING.

Re: Satellite radio--XM vs Sirius

Our GLK350 has SIRIUS from the factory.My E320 has XM. Our experience over several years is that XM has a stronger signal with fewer dropouts that SIRIUS.

Re: Satellite radio

Jim,

Sounds like you've done a really nice job on this.

Where did you mount the satellite antenna?

Ideas on this would be especially appreciated, as I am considering upgrading the factory stereo in our Honda to a bluetooth compatible, navigation head unit with satellite radio but one of the issues I am researching is how to mount the antenna for the satellite radio without butchering the car. That's the appeal of a factory solution generally, to me at least.

Thank you in advance.

If the antenna was not a problem more people would have satellite radio in their cars.

The only reason I put one into the CL is that the antenna was able to be completely hidden, out of sight. The satellite antenna is installed inside the trunk, since the trunk in the CL is made of composite material (plastic) that allows the signal through.

Re: Satellite radio

I have a similar question. I just purchased a used 2006 E320 CDI, I have the satellite antenna mounted on the roof, but when I press the SAT button, the screen says "No SAT Radio". The screen does not give me any options to call SIRUS to activate. Since I believe that the antenna is for the satellite radio (unless it is for the navigation???), shouldn't this work?
What will it take to make this work?
Thank you,
Mike Trevelino

Re: Satellite radio

A couple of more questions.
If your car is prewired for the SAT radio, what exactly does that mean? I am also running into this when I hit the TEL button, it says "TEL NOT INSTALLED".
Thanks again!

Re: Satellite radio --Antenna placement

My CDI is black/black. The antenna is black. Placed the antenna on the dash as close as possible to the windshield approx above the glovebox but away from the A pillar. Reception is no problem and with my color not really noticeable. Also makes for easy installation and no wires showing. Keeps the outside free from the antenna showing and weather problems. I have used this method on 3 MB's.

Forgot to mention that all this can be done without interfering with the lighter operation which I can use to charge my cell phone etc.

Re: Satellite radio-Mike's problem

1 Is the roof antenna for satillite factory or after market?

2 To my knowledge your car (same as mine) is not prewired for sat.

3 If your roof sat ant is NOT FACTORY then it sounds like the previous owner took the sat. receiver out and left the ant.

4 Contact the previous owner or have a tech check it out to see what you have to work with.

5 Just because there may have been a sat receiver previously installed does not guarantee that it was correct. Some times it is better to start over as I know from experience that there are wrong installations. I had one.

6 If roof ant is factory then you have to go back to MB.

Re: Satellite radio

Thanks for your reply Jim. I am going to the MB dealer tomorrow to see if I can get a print out of the original window sticker to see what was installed from the factory. I also need to talk to the service advisor to see about what maintenance I may need.

Re: Satellite radio

When checking with my dealer about installing satellite radio for my 2005 E320 CDI, they told me the parts are no longer available for installation through the pre-wiring into the COMAND unit. Any ideas about places other than a Mercedes dealer to go to find the parts (not after market; i.e. Potomac German Auto in Maryland)? Is there any "blanket" way to put out a message to Mercedes parts places around the country to find the receiver?

I would check with another M-B dealer to confirm that the satellite receiver for your car is no longer available, because I find what your dealer told you hard to believe.

Re: Satellite radio-Mike's problem

Sorry for the late reply to this. The rooftop antenna is for the "emergency" system that comes with the car. From what I was told by the Service Adviser, my car is NOT prewired for satellite radio, but I pulled the rear side panel away some and did see what looks like a fiber loop (with a square chrome connector), and saw what looks like a electrical connector (wire tied). I am researching the satellite radio option from Cartronics. The link to their website is:
