    Here is the 700TSV with the bezel:




    I did not have the NAV car so I had to buy the conversion part to drop the the AC Controls:


    Here is the Super VEN4 (Unbalanced RCA -> Balanced):



    Ok, since the Audiophile puts out a +4 signal here is the Audiogate line driver thanks to Zebel for suggesting the super ven / Soundgate (this will be a temporary solution until I put in a system):




    Here is the soundcard that drives the audio to the system... This soundcard is great since it is made by Avid; Since it is firewire the mac will power the soundcard off the firewire bus, and its M-Powered for digidesign software!:

    looks good. i a little confused though... your stock system is looking for a balanced line? why didn't you just get soundcard with balanced outputs?

    what are you initial impressions of the car pc? do you like it?

    now lets see the computer!

    Yeah, my stock amp is a harman kardon amp that wants a (hot + / cold -) per chan / and a shared common. So I have Front L +, Front L -, Front R +, Front R -, Back L +, Back L -, Back R+, and Back R -, and ground.

    Pictures coming soon of the computer.

    Sofar with GPS, video, DVD, and music capabilities... I am loving it; except there are a bunch of really small things that will need to be tweaked.

    so could you have bypassed the interface if you just got a soundcard with balanced outputs?

    I absolutely could have gotten a soundcard with balanced outputs, however I plan down the road to get a JL amp with RCA inputs; so the interface is just a temporary converter. I probably could have gone without the SVEN (green box) and just converted the RCA to balanced by doubling the tip and using the ring as the shared ground.

    Sweeet!

    I am glad my audio solution is being adopted in your install. M-Audio is a great device. As for the SoundGate, someone told me that I could get a used Audio Control 4ch linedriver for the same price, but I think the SoundGate you and I got seems to do a good job, may be I am getting too old to hear the difference.

    Just wanted to give you heads up on M-Audio, You may find that the Windows volume control does not effect the volume for analog and spdif inputs. It only controls the vol for SW return (any audio that is coming out of the FireWire lines). So if you are planning to use the analog and spdif inputs for audio coming from, let's say, a radio card or Sat radio then you may notice that Windows volume control does not change the volume at all.

    To make it work. I had to write a program that runs in the background and monitors changes in the master volume and change the leve of both anlog and spdif inputs acordingly. In my case I am using a Sirius Sat, the interface dished out optical which I have connected it to the spdif input of the M-Audio, - I used an adapter.

    It seems you have not picked your FM and Sat radio yet. Let me know if you are running into this issue too. Just curious!

    This is very interesting, I had not played around with any of the inputs (SPIDIF or otherwise). I am considering integrating a USB FM solution into the project, since my passengers seem to like the radio. Personally, I'd rather use my MP3 collection and not radio in any fashion (sat or local). Sofar I really like the audiophile since it can be self-powered from the firewire off my computer.

    Ok, here is an update of what is going on with the project... I acquired an Intel Mac, a CarNetix 120 watt dc-dc power supply, and a "Mac-Pac" to hook up into the mac mini. Installed onto the mac mini is roadrunner with the e36 skin.

    I was using ressler's iBus interface however it started to give me trouble with the iBus. When the iBus was conected to the interface, sometimes when I went to unlock the car the audible chirp somtimes would not happen; the lights that flash would not flash, and somtimes the turn signals would not work. So for now, I am going to stay away from the iBus (since it is only sporadically working). I probably shorted out my interface somehow and need to acquire a new one. However while it was working properly, I did have it so that it could do VOL UP and DOWN plus next track and last track.
