    As for pictures, I didn't take any when I did it. What I did though, was grabbed hold of that blue window with a pair of pliers. I slowly pulled and wiggled it out. Originally I thought it was just a BT dongle glued into a USB port-- lol, no such luck. The blue window actually holds the radio, and it is nearly the whole length of that port riser it is in. The back side of the blue piece is very thin plastic though, so it eventually broke leaving the radio in it's place. I then removed the shield for the back of that set of jacks (maybe should have taken this route first) desoldered the stock radio, and bent each of the pins 90 degrees and then stuck my little USB dongle in their and soldered each pin to the corresponding pad on the usb adapter. Here is a link to the USB dongles I bought ebay clicky. That is the exact same auction I used, but I couldn't guarantee the dongles are still the same, it has been a few months. The dongles come apart fairly easily, just peel back the shield and they pop apart. The radio is about the same size as the one I jerked off the board.

    FWIW, I wouldn't dick with it if you don't have a decent amount of solder/rework experience. You will be working right above the MB where an errant drop of solder will likely ruin your day. If I have to take it apart for any reason again, I will snap some pics for you, but I don't foresee needing to.

    Thats not good news. One of the reasons I chose this board was for the built-in bluetooth. Thought I was done w/ My PC. Looks like I have some more work ahead of me.

    Thanks for the info,

    Well, the slot did not come out as hoped for. When I pulled the drive out, it was a lot tighter than expected, and first off I broke the upper portion of the slot, where it was very thin, right off. I wasn't to worried about it, I was going to make a new top part of the slot out of some scrap aluminum. It is pretty unlikely that you will even be able to see the tip of the slot, this is going to be right up to the edge of the dash, and it overhangs the radio bezel by probably close to half an inch.

    I put the drive in w/ none of the stuff covering it up anymore, and I really didn't like how the slot was coming. It needs a felt back like the factory trim plate, that makes it look a lot better. So, on to plan b, I cut the stock trim plate in half and wrapped the actual drive I was going to use in foil. I put the trim piece on that with just small dabs of hot glue. I started modifying the work I had already done to fit the slot portion of the face and flush it in with rest of the bezel. I had to file away a good portion of the epoxy that was there, and in the process I broke it away from the polycarbonate piece. Turns out I didn't have a good bond, and it is fortunate I ran into these problems or it would probably have cracked down the road and really ****ed me off.

    I ended up re-doing this with my good drive-- hopefully I don't ruin it. Bellow in the pics you will see what I am shooting for this time. hopefully it will work out better. I might get a chance to screw with it a bit tomorrow, but I am off to work midnights tomorrow night, so I may not get free time being Christmas eve and all...



    I cut a groove in the polycarbonate to help lock the epoxy into the rest of the piece. This edge is where it broke loose last time around.



    The fit with the HVAC controls turned out good, it still needs a little bit of work to get the lines perfect, but it is close



    Here is a shot of what I filled. The slot half of the trim piece has a piece of dowel split in half and lightly glued in place. The plan is to sand it all with the dowel in place, when all the finish sanding is done, pop the dowel out and hopefully have a decent slot with minimal finishing that needs done.

    Well, I had an update to go between today's and the previous one here, but my camera ate the pictures, so you will have to be without some pics.

    Yesterday I sanded out the epoxy I laid down to see how my integration of the oem faceplate went. It actually started out really good, but I got a bit carried away sanding out the demarcation line between the slot and the filler and I butchered it pretty good. By the time I realized there was no fixing it, it was going to need a lot more filler and hand shaping to get it right again, so I once again scrapped it and started over. I honestly was about to ditch the DVD drive all together...

    So, on to plan... uh... c I guess??? Any one keeping track? Anyhow, I drew a slot and filler piece up in CAD, did the CAM work and ran it off on my CNC mill. This piece isn't perfect, but it is pretty damned good, I can live with it. It still needs a felt backer, and lots of filler after the glue sets. It is glued along it's lower length with loctite 404, basically just industrial strength super glue. Once it sets I am going to "v" out all the joints and fill it with epoxy, then sand it out and go back to body filler. You may notice in some of these pics there is a light blueish tint to some of the epoxy now. I already did one coat of body filler before I scrapped the last drive trim.

    Here are the pics:

    It's a two-for today! The glue set up and I had some more free time so I went and grooved the joints and laid down more epoxy. With any luck the way I got it taped/masked I will level out the top as well as fill all the joints.

    Here are the pictures, I'm off to work on day shift tomorrow and am working through the weekend. It will be next week sometime before I get to it again. With any luck it will come out right this time because I would really like to move on to start mounting the electronics.

    Finally! A ray of hope!

    Took a few minutes this morning and sanded out the epoxy that I laid down last week. I finally have something that resembles the picture in my head. I can definitely live with this result. The pics bellow all have the drive installed, a felt backer for the slot and it will be as close to perfect as I am likely to get it. So, at this point, I am looking at a bit more filler for the bezel, then paint and it is on to mounting electronics. Actually, I will probably do the filler now and wait on paint until it is ready to go in the dash. I don't want to spend a bunch of time on paint and then scuff it up while fabricating the mounts/enclosure.

    So, tell me what you think? I am considering mounting a single led centered in the bottom of the slot. I would current limit it pretty low and keep it dim, or maybe even find the "media in" switch in the drive and light the LED only when the drive is empty... Just thinking out loud, give me your thoughts.

    Here are the pics:

    I got some more done this afternoon. Put down another coat of body filler and sanded it out. The pin holes all look to be filled now, it looks pretty good to me.





    Then I started test fitting the electronics. The plastic cage is just the factory Double din mounts. I split this part from the bezel early on to make things easier to work on. I originally thought the screen was going to interfere with putting it back on and was planning to fabricate mounting stuff from scratch, but a little fine tuned epoxy removal on the back side and it went back together with very little problem. The plan here is to cut some .125" aluminum "shelves" for lack of a better explanation. there will be a solid aluminum bottom plate for both the monitor electronics and for the MOBO. I am going to do the CAD/CAM work later tonight for the mounting points for both boards, and drill them on the CNC. I have all the standoffs that I will need to mount the boards properly.

    The pics are just for mock up. At this point, it looks like I will be able to mount the hard drive directly underneath the MOBO and probably the DC-DC supply as well. I have not yet figured out what is going to happen with PCI-e video card, I have a flexible slot extender, and I have mocked up a few locations, but it is to difficult to hold the MOBO and try and juggle that card and extender around. If there were enough room behind the DD opening I could just plug it straight in it's slot, but it's to tight in my dash, the heat sink would hit the heater core plenum behind the dash. Anyhow, I will make the board mounts first, and then figure out the video card once things are better contained.

    On a side note, there is about an inch between the CPU fan and the bottom of the DVD drive. I tried to get a decent shot of it bellow. Does anyone have any input on whether or not this will be enough room for reasonable cooling? I can go lower with the MOBO, but it will mean major surgery of the DD mount and a lot more fab work to get the skeleton that will remain to support all the hardware.

    Nice! Will you retain your cup holders or is that where the DVD is?

    The factory cup holders in the '01 are above the radio, basically where the DVD drive went. A year and a half ago when I put in my Eclipse 7200MkII I moved my HU up to the uper din pocket because I liked the layout a bit better. When I did this, I lost the functionality of the cup holders. I purchased a used center center console from a '04 Jetta (iirc), these consoles had two cup holders in them, you either have to buy a complete new E-brake assembly for the '04 or be willing to do some persuasion to the earlier one.

    All in all I hated the slide out cup holder any how. I am normally rocking a big 44 Oz cup, so while the factory cup holder worked, it was just marginal. I love the center console ones, so it is well worth the investment

    Yeah, I knew about the cupholder update in 04, and I saw your car was an 01, which is why I asked. I still use mine above the screen even though it is in a bit of a precarious position and partially blocks the screen when in use. I'd eventually like to get the center console update and put a slim DVD above the screen where the cupholders are now.

    Well, for what its worth, the dvd drive barely fit up there. You can see where I cut back the plastic on the drive mount, this was simply because it would hit the bottoms of the switches above, but there is a bit more room further back. I imagine with a 7" screen instead of the 8" that it wouldn't be an issue. I literally had almost exactly 12.7mm left for the drive.

    As for the console, I bought mine on ebay for I think about $30 shipped, I got one with a broken screw hole, so it was cheaper. A little bit of time with some epoxy, a file, and drill and it is good as new. The stock e-brake will work, I was able to bend mine enough with just my brute force in the car Anyhow, pick one up when you can afford it, it is well worth the time and effort.

    Btw, no update for today, I got the cad work done for the aluminum pieces last night, was going to run them on the cnc today, but life interfered with my plans. I had to watch my girls for a while, then I had to snow blow, then my mean machine snow blower's chute fell off and I had to weld her back together, anyhow, took a big bite out of my day, and I am back at work on midnights now.
