  • 2005 Volvo S40 Advice/Worklog

    So as of right now I have a pretty general plan. Once I get things going itll turn into more of a worklog.

    Here is a pic that explains my situation a bit. Its about 1.7MB.

    The inside is Fiber Optic so hopefully Ill be able to hardwire the audio in, even if that means removing the CD Player. Worst comes to worst Ill use an FM Modulator.

    I play on getting an M1000 mini-itx board, 512mb ram. the mi-atx 90w psu, a valentine 1, vga touchscreen (no idea which model), and a 3.5HDD. Ive yet to find the cord but im pretty sure the fin on the top of the car is for GPS so there should be a wire for it somewhere in my head unit. I will be mounting the case (which Ive yet to choose) in the trunk. Ill probably be incorporating the ODB-II system and the valentine1 into the carpc. If possible, maybe ceiling mount a flip down screen in the back for watching movies.

    Ive never seen anyone put a PC in a s40 2005. Hell, the pics of the optional navigation are rare enough. Anyone have any insight on how to go about doing this?

    There are still a few things I need to determine, such as how many DIN the CD Player & FM take up or how I will mount the LCD on the top (if aux in allows me). Ive tried taking apart the head unit to get a look on the insides but I mustve been missing some screws because it wouldnt budge.

    The inside of WHAT is fiber optic? The only thing that I could possibly see being fiber optic is anything that transmits data. That could be the CD player and/or changer and any data display. Possibly electronic climate controls and the like.
    Fiber optic lines aren't cheap. They're also glass, which means they are fragile. Those two qualities make them less-than-ideal for a vehicle application.

    Look at the Show Off Your project forum & the FAQ Emporium forum. Most of your answers will be there.

    There are still a few things I need to determine, such as how many DIMMs the CD Player & FM take up or how I will mount the LCD on the top (if aux in allows me). Ive tried taking apart the head unit to get a look on the insides but I mustve been missing some screws because it wouldnt budge.
    You mean DIN, which is a standard size for car audio equipment in the dash. DIMM is a Dual Inline Memory Module, which is RAM for your computer.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

      They use MOST for the wiring of the CD Player/Radio to the speakers. I dont know much about it I just know all the wiring is fiber optic. Id take a closer look to see what it is but I need to get that head unit off first. Yes I mean DIN. *changed*

        ill be...

        "The new M.O.S.T system (Media Orientated Systems Transport) is a multimedia fiber-optic network optimized for automotive applications. It connects a variety of systems that need to communicate - the GPS navigation has to work with the security system, the car telephone has to work with the entertainment system so it will mute when a call is received, voice activation and hands-free speakerphones require a microphone, and a display is needed for navigation and DVD playback to name just a few."

        still sounds like they are talking about your data bus though, not your speaker wire

          I dont know exactly how it works, Ive just read over and over that it is very hard to get an aux-in, even when replacing already installed components.

            I have the same problem with my XC90 - MOST is the biggest PITA going.
            However if you can get hold of the wiring diagrams for your car the output of the AMP to the speakers is not Fiber. I'm in the process of ripping out the stock headunit, replacing it with an Amp and then using the output of my CarPC to drive the speakers - EASY!
            Then its a case of adding what functions you want to the PC to replace what you had and add more.......
            A good place to start for wiring and Volvo help is www.vvspy.com
            Good Luck - look forward to seeing the install

              Thanks a lot klokman! What you said about MOST clears up my understanding a bit and that site looks helpful! Im looking now for some wiring help/diagrams.

                Little update. The sharkfin is in fact for GPS. I managed to get ahold of the electrical schematics. PM me if anyone wants it.

                  Silv3rman, Just in case you thought it was going to be plain sailing..... I started on my amp last night and found out that the XC90 amp has integrated crossovers (I presume the S40 is the same), so you'll need to add some of those to your shopping list - or things will never quite sound right!

                    Just took a look at your picture.

                    Well, if the Volvos bus can be hacked like the I-Bus, you should be all hooked up integrating the buttons on your Steering wheel into the system. That would be sweet, although, I am truly unsure if anyone has done that.

                    Next, where your navigation syetm would go seems like an ideal place for a screen.

                    I would remove that panel, and see how much room you have underneath there. You could then do one of several things. Hopefully there is enough room to fit most of a motorized screen in there. I would either sink the screen in there, leaving the top part where the screen come out of just above the line of the dash. I would then take that panel that you removed, and add some bondo/fb to make it sit on top of the screen, of course filling in the sides and back so that it fits the dash correctly. In that way, your screen will pop out when you start the car, and in when you turn it off, and you can keep your stock headunit.

                    The other thing youo can do, is mount it int he space under the panel, but angle it up. You would have to bondo as well, but it will be different. It wouldn't be this "hump" on the top of the dash, it would be more of a bump, with a screen that come out of it.

                    I have attached a couple of drawings to show what I mean

                      Thank you for the heads up klokman. Thanks for those ideas Wiredwrx, I agree and Im considering both of those. Ill have to take off the head unit this weekend and see how much space there is. Now Im not an electrical engineer and this PDF isnt exactly the most easiest thing to understand but, I dont think they use I-Bus. I think they use LIN or something. Ill have to re-read the PDF and get more of a grasp on it. For those who are interested the PDF on the electrical schematics is here: http://silv3rman.us/volvo/opr064OM.pdf

                        Curious why you are taking the stereo out?

                        Just to clarify, my idea involved adding a motorized screen to the area in your pic that you circled and wrote "STOCK NAVIGATION WOULD BE HERE
                        FLIP UP SCREEN WOULD BE POSSIBLE"

                        In my pics, the front view is how it would look while sitting in the seats. In essence, the screen would look like the following crappy paint drawings.



                        You would keep your existing HU, and the buttons associated with it, and just add the screen to the top.

                          I dont want to take out the stereo. From what Ive read I figured I would have to since there was no other way to get an aux in. Im still not clear as to how I will be wiring all these. My ideal situation would be to put it where you have suggested, keep both the CD player and the radio and somehow have a button for the computer's sound. I was thinking about possibly having the top LCD be for the navigation only and have the bottom LCD (where stereo currently is) be for all the music/dvd/etc navigation, but not anymore. Id much rather keep as much intact as I can and still achieve a functional carpc.

                          Nothing like dreaming.. http://silv3rman.us/volvo/someday.jpg

                          Ooooh! I think I get what you mean with the LCD. So I would basically just mount it above the speaker already there and probably bondo it up to look nice, no dremeling or anything?

                            Well, AUX in isn't always possible on a stereo.

                            HOWEVER, I am reading that PDF, and there is some good info. First of all, CAN is a standard. If you search for CAN Bus, you will find lots of information.

                            The other thing is, it looks like it uses the K-Bus. I believe that is the same Bus that is used on the New Mini, and it is very similar to the I-Bus.

                            Time for some Internet searching.

                            I searched Blitzsafe.com, and PIE, and while Blitzsafe is working on an XC90 product, which will probably work with yours, Neither of them have nothing for the S40 right now. I have a feeling you knew this already.

                            Perhaps the Volvo forums can be some help with the data bus.

                            Michael

                            I used an tape adapter for years. Ya, not the greatest sound quality, and the whole wire thing, but, it worked.

                            Michael

                            From a site talking about the Mini
                            "Plug-and-play
                            The multiplex electrical system connects the engine management, braking, transmission, and instrumentation computers through a CAN-bus, while the body electronics (lighting, windows, door locks, air conditioning, etc.) are connected via a K-bus system. By integrating these systems, as well as the sub-systems on each bus, the engineers were able to reduce the size and weight of the wiring harness, as well as introduce a "plug-and-play" capability: options, like the rain sensor, navigation system, or auto-dimming rear view mirror, can be integrated into the system through simple software changes. Plus, should the need arise, drive-by-wire systems can be added as they come on-line."

                              Thanks wiredwrx. Time to search for "CAN" & "K-Bus". I grabbed this off another forum. Im pretty sure it was for the S40, but I forget what they were saying about it.: https://www.eurodrivegear.com/script...?idproduct=127 . Is that the same product you said they were developing?
