2006 VW Passat Variant CarPCed (56k beware!)

So since the headunit is in the glovebox, and the pc is in the trunk (more or less) did you have to run the pc audio out wires up to the headunit's aux in, and then run headunit's output to trunk amp? If so, did all of this long-distance audio wiring introduce any noise to the sound?

@hark: yes, this is exactly the wire setup. Luckilly there is no interference and extra noises, it just seems that some interference was introduced into the monitor signal (or monitor power), since in certain cases you can see some horisontal lines running on the monitor. It's powered from the computer PSU, so the voltage should be stable, but it's not 100%, apparently.

i love it. i have an mk5 jetta similar concept,
i was talking to enfig guys @ www.enfig.com, they will be making a module that our amp will sense to activate,( so i could directly run audio out of the pc i should get a beta in 2 weeks,

i love your intall. also did you have to do any trimming to get the headunit into glovebox

thank you thank you.

dude it looks really good. however....it looks like you used hot glue..trust me through experience myself that **** is gonna crack unless you peal the hotglue out and use some epoxy..just a heads up.other than that great frikkin job man

Great job man. Just a question.

How is the sound quality of that sound card??
Does it work well with the SP13000 or does it take much of its processing power?

@Yevmeister: what kind of module do you mean there? One that turns on your remote (in my case the power supply does that) or something else?

@eskalad: the hot glue was used to hold the monitor frame into the bracket, on top (=the front of the monitor as is seen now from the car) it is epoxyed. Hope this doesn't crack - or do you think anyway that also the glue from the sides should be kicked out? Now this will start to concern me

@ramy: sound quality is good, I think much better than the original form the mobo. It works without a problem and I haven't seen any measurable difference in processor usage compared to the onboard sound. In theory it should require less power since it is a hardware chip compared to a software emualtor chip on board... it's true though that I haven't been running it in the car to see whether there would be any more distortion from the on-board soundcard compared to the XFi, I was just trying it in my office. I'm not sure though I'd go for such a setup again - probably I'd just use the on-board one since there is so many other noises in the car that little differences in quality can't be really heard... But hey, if it's laying on my desk, why not use it?

no module which can bypass pc stereo directly into the amp without headunit attached.

i have been trying to connect audio in my car for months now, but in your case since you have steering sound controls and you would like to keep them that would be the way to go

I'm not sure I really get it what this module would do. Do they have something similar for other cars as well, what would this module interface between?
What I mean is that my original idea was to connect the PC directly to the amp. No probs, the front speaker output would be split to the woofer input and front speaker input, the rear would go to the rear speaker input. The steering wheel controls would be passed to the computer using a can-bus interface adapter (some debugging would there be needed to find the right signals). Though the biggest concern at the end was that I don't have a normal tuner anywhere that would feed me RDS information and that would then work with the PC frontend normally - that's the main reason I went for the HU then.

Very very nice install. I love those cars too, they're just soo good to drive.

Well that's odd because i can't get the audio with that method. my simply doesn't initialize

i voltmetered signal, and there is an output
