The volvo web site indicates that the headphone connectors mounted on the c pillars in the back allow 4 rear seat passengers to listen to different sound sources simultaneously. How does this work? Does it mean 1 can listen to the radio while another listens to a cd? I don't think it means that 4 people can listen to 4 separate cd's or radio channels. Does anyone out there know for sure?<p>Thanks

Re: headphone connectors for the XC90 (XC90FANSCOTT)

It does work. You can listen to a CD through the headphones while the front passengers listen to the radio. Now, the headphone users do have to listen to teh same source. If both the front passengers and th erear passengers are listening to the same source.. the front passengers have "control" of the selectons.

E.g. one can listen to CD, another can listen to MiniDisc and a third can listen to radio while the front seat passengers listen to the radio (or any other source). However, you can't listen to different CD's from the same player at the same time or different radio stations at the same time. But if the headphone is connected to the same source as the speakers the speakers have control.

Re: headphone connectors for the XC90 (XC90FANSCOTT)

I took a set of headphones down to the garage tonight, since I haven't had a chance to test this out.<p>If the front passengers are listening to the CD player, the back passengers can either:<p>-listen to the same CD as the front passengers--but they don't have the ability to change the tracks. The volume to the headset is adjustable, however.<p>-or they can listen to the radio.<p>There are 4 headset connectors and each connector has a volume control & 3 buttons. The buttons are: SEL-which selects the audio source; and a forward button and backward button, which allows the user to scroll through the radio presets or the CD tracks, depending on the source selected.<p>I don't have the mini-disk option (it was never mentioned to me and I don't see it in my literature).<p>HTH<br>

Re: headphone connectors for the XC90 (Sharon)

Sharon --<p>It gets a little tricky, and Yannis can probably explain this better than I can, but I have two small kids, and we recently purchased headphones as I'll have to kill myselif if I hear "Joseph and the Technicolor Dreamcoat" one more time (just kidding).<p>One kid's not a good test subject as she's only two.<p>I read up on this in the manual so I feel like I have a general understanding.<p>I believe at least three different sources (and no more) can be listened to. Driver controlled (speakers), left rear passengers, right rear passengers. As you know, each side has one docking station for headphones, and each station has two inputs. So (to beat a dead horse) I think the right rear passengers can share an audio source and the left rear passengers can share a different one and the adults can share a third.<p>Where it gets tricky is when the kid is toggling and so are you. We had two "incidents" during a 90 minute trip. Both times, our messing with the main controls (to hopefully hear some grown up music) while a child oriented CD was playing caused the child to end up with a toggling choice between two sources other than the previously mentioned child-oriented CD. Whether "Joseph" was still playing is unclear to me.<p>As you probably can tell, I'm still trying to figure this out myself. Especially since we had Uncle Kracker in the disc changer (we're not especially young, I just like "Follow Me"; also, we (adults in front seat) were only trying to hear the radio so we don't even know how the CD got changed) and of course one of the two incidents involved me hearing all kinds of obscenities through the headphones when I pulled over to try to figure out why my son couldn't hear his CD.<p>I do think I'm figuring it out. Front seat passengers trump everything. So back seat passengers don't truly have freedom of choice, except in a limited manner. I just need to figure out the rules of the game.<p>Hope this is useful. <br>

If you have kids in, say, the left side second and third rows, they can each listen to a different sound source. One can choose radio, the other, CD. They don't have to share an audio source. One more sound source would be great. Hey, maybe they will come up with the MP3 option as a different source! <p>I haven't let my kids use the headphones yet because I don't trust them to listen at a safe volume. I'm going to have to break down and buy a few more sets of headphones, soon, I'm sure.<p>Sharon

Re: headphone connectors for the XC90 (Sharon)

Do you think there's still a total of three sources? I swear I read that somewhere but that's inconsistent with 2d and 3d row passengers on left side choosing independent sources and 2d and 3d row passengers on right choosing independent sources unless each row somehow must agree (which seems less likely than each side agreeing since the passengers on a side do share a docking station).<p>I guess I could take four headphones downstairs and try it out. But I think if I read the manual now having actually physically tried it I could probably figure it out.<p>How old are your kids? Must be older than mine (5 and 2) if they can reach the volume button. Thus can't they be trusted?

Re: headphone connectors for the XC90 (eaton3000)

There are only two sound sources (CD & Radio). If you have four people listening to on headphones, they are going to have to work out who has control.<p>My kids are 11, 9, and 6. The six year old sits in the middle, most of the time, so he won't be able to reach the volume (I'll have to get a set of headphones with a long cord) but the others can. And they love their music--loud. Don't we all <IMG NAME="icon" SRC="http://********************/smile/emwink.gif" BORDER="0"> <p>Sharon<br>

Re: headphone connectors for the XC90 (Sharon)

OK, AudioGuy to the rescue!<p>Here's how it works:<p>The audio system is a multiplex bus network that operates at a very high bitrate. This techno mumbo-jumbo means that all audio sources are available to all audio outputs (almost) independently.<p>I.e. all audio sources feed their music to the bus and all audio outputs tap in to the bus and extract whatever source they are interested in.<p>Since the XC90 system is very flexible and future-proof we will be able to add more audio and video sources as they emerge. Right now the maximum is three (AM/FM, CD and MD) but it will grow with things like DVD, digital radio, TV etc over the years. So at some point there will be more sources than outputs but still full freedom to choose any source at any output.<p>So to clarify: ALL four headphones are individual and not dependent on each other even if they happen to be grouped in two panels with two outputs each.<p>The only limiter to the freedom is that the front seat (speakers) have priority over the source they have chosen. But as long as you listen to radio over the speakers the headphones can control the CD's. In the case with Uncle Cracker I suppose that Joseph had run to it's end and then the CD changer changes to the next disc.

Re: headphone connectors for the XC90 (Audioguy)

Thanks for explanation. <p>Here's the ultimate question from me: can two different CD's and two different radio stations be listened to at the same time? As is probably obvious, I'm not very technical. <p>I think you're right about Uncle Kracker. Joseph was CD 6 and Uncle Kracker was CD 1. Now it makes sense.<br>

Re: headphone connectors for the XC90 (eaton3000)

No, that can't be done. Can't even have two stations from different bands (e.g. one from AM and one from FM.) since the radio is just one source. When a change is made to one source, everyone listening to that source get changed as well. (i.e. If I jump to Disk1 Track2, everyone listening to CD will be affected.) <p>With just CD and radio in the US, when are we going to see other components for sale? Are they in developement now? Will Volvo be the only provider or will we be able to add other 3rd party equiptments and intergrate them? <BR><BR>

Re: headphone connectors for the XC90 (nomis)

So, not to beat a dead horse or anything, given that my only input choices are radio and CD, the only output choices are radio (one station at a time) and CD (one track at a time), right? <p>As those more technical than I have pointed out (if my interpretation is correct), the four back seat passengers can collectively pick either one track of the currently playing CD or one radio station.<p>What happens if one "headphone" passenger advances the CD one track? Does any other headphone CD listener (assuming CD not on speakers) advance as well? Seems that would be logical choice. Now, what if one headphone radio listener advances to the next radio station (assuming radio not on front speakers)? I guess all headphoners must advance. <p>I recognize that the front passengers must be listening to something, which would muck up the purity of the above example. But just for fun, can we assume they're not in conflict with back seat listeners?<p>Thanks in advance for any and all assistance.

Sharon --<p>Thanks for your reply.<p>As I'm sure you know, it is not just a boy thing, or an older child thing. My pre-literate boy and girl would fight over a piece of lint.

And, yes, this setup does require agreement between all headphone listeners who are listening to the same source if one of them wants to change track/station. We thought long and hard about this, one idea was to let the first listeer that chose a source have control but we realised that would only create new problems. If anyone out there has a brilliant suggestion please post it here. <IMG NAME="icon" SRC="http://********************/smile/emsmile.gif" BORDER="0"> <p><BLOCKQUOTE>quote:<HR>With just CD and radio in the US, when are we going to see other components for sale?

Can't say release dates yet, though. You can already now add a MiniDisc player to your XC90 if you want to. Since each car maker has its own dialect of this MOST bus it will take some time before any mobile electronics manufacturer ventures into making a 3rd party aftermarket component for the MOST bus. Besides, they are all pretty busy designing and manufacturing the OEM components for the time being.<p>So in the close future you will have to suffice with Volvo components. Since Volvo, Jaguar, Land Rover, Aston Martin and Ford are the same company and Volvo is appointed centre of excellence for Infotainment it is more than likely that some Volvo components will find their way into Jags and Land Rovers and of course vice versa.

Re: headphone connectors for the XC90 (Audioguy)

Thanks Audioguy! I think many of us will be waiting eagerly for the new options. <p>Personally, I would like to replace the standard CD player with one that can decode MP3s. That should still leave space in the other slot for either a cassette or 8 track tape player when those components become available. <IMG NAME="icon" SRC="http://********************/smile/emwink.gif" BORDER="0"> <br>
