I have a 2000 <br>
S class and want to install a Sony XM head unit with fm <br>
modulator. I already have the unit and want to mount it <br>
in the glove box. Several questions:<br>
<br>
1. Where is the antenna jack for the Command unit and is <br>
it a standard Motorola type jack or something else?<br>
<br>
2. Is there a way of inputing line in on the Command, as <br>
there appears to be an empty button across the top (e.g. <br>
radio, cd, etc).<br>
<br>
3. Where would be the best place to take power from if <br>
the head unit for xm Sony is in the glovebox, and<br>
<br>
4. How to route the antenna cable from the rear trunk <br>
(and how to get it in the trunk from the rear roof just <br>
above the window) thru the car to the glove box? I have <br>
heard the usual best way is thru the trunk to the door <br>
sill but not sure about this. How to get wire from trunk <br>
to door sills and how to route thru same? Or is there <br>
another option.<br>
<br>
Many thanks for any help.

Stephen, I didn't answer your first post because I don't know much about your car, and I was hoping someone who does would respond.<br> <br> 1. I have been told that the Mercedes antenna jacks are not standard.<br> <br> 2. COMAND has an auxilary input. In the C-class, it is in the glovebox because that is where the CD changer goes. If the CD changer for the S-class goes in the trunk, it is probably there. <br> <br> 3. In a C-class there are some unused fuse positions in a fuse box in the trunk. I'm sure there are other acceptable locations also.<br> <br> 4. Several people have mounted the antenna on the package shelf near the third brake light. This makes the wiring easier, and there is no unsightly antenna on the exterior of the car. It is not quite the ideal way and may result in some signal loss, but the people who have mounted the antenna on the package shelf are happy with it.<br> <br> If you can use the aux input, use it as the RF modulator degrades the sound quality somewhat.<br> <br> You might go to http://forum.mbworld.org/ and do a search for XM. There are several threads, including some showing both Sony and Pioneer recievers installed in C-coupes.

I just got the Pioneer XM FMTUNER model added to my 2002 C230. There is a non-standard antenna connector on the MB, but the audio shop I used had adaptors in stock (two are required). Just call around until you find an install shop that stocks these.

A quick search in Google found a couple places that sell these adaptors. Here's one: http://www.premieraudio.com/ppl.html<br> <br> I'd advise calling them to make sure you get the right 'flat european antenna' adaptor. You need two. One from antenna to radio to plug into the modulator. And one from radio to antenna, to plug into modulator.
