Here is my latest project.

A free 3D model of the Center Instrument Panel for the B3/B4 chassis that allows for a Double DIN stereo install. Center vents are deleted.

I've thought about doing something like this a lot. Like varia said though, I use the vents area for gauges.

This is awesome!

Any way to keep the vents and remove the bottom gauges? I figure a guy should be able to use a screen that can show gauge inputs and not have to look down so far. Not sure if the HVAC would still fit though.

Thanks y'all. It's been a rewarding project.

I haven't had center vents since I did a CarPC install in this car back in 2005, so I don't miss them. :-)

I like the option of sacrificing the OEM triple gauge panel for extra space.

Take a look at the included picture. It wouldn't be one piece without chopping up the dash, but definitely do-able.

1: Use OEM top half of instrument panel, saving vents and switch panel.
2: Model a Double DIN bracket to use below that
3: Relocate the HVAC to the space used by the triple gauges. Wouldn't be too hard to make an adapter panel for that purpose, and the wiring should all reach. The digital climate controller is actually pretty small, so I think it will fit.

I personally like the triple gauges so won't be doing that, but for folks who really like their center vents it could be an attractive option.

Next time I have my center console out I'll take some measurements.

Definitely interested in more details about the CarPC install. What functions did it perform? What model did you use? Is it similar to using an Android tablet?

I have plans of using a tablet as a touch screen nav unit, a music storage device and (most importantly) a real time data display for VEMS. So that's why I ask.

The triple gauges are a very desirable characteristic of the car, no doubt. I think they're very, very cool. Unfortunately, they're poorly located for any real performance driving, for my tastes, at least. Hence the notion of using a tablet located higher up. Since I like the vents and don't want to sacrifice them I was planning to find a way to mount a tablet to the dash trim above the glovebox. I figured that would allow good ergonomics, and be easily removable for security/upgrade purposes.

After it warms up, and my friend and print in his garage again, he is going to try to print one of these in ABS for me. Hopefully it comes out ok the first time. 34 hours of print time will suck to have to do over.

Flashback down memory lane.
The car PC was basically infotainment/navigation at a time when such things were only available in very high end vehicles.

This was in 2004-2005, 3 years before the first iPhone, and over 5 years before the first iPad introduced the world to truly mobile computing.

I had a 7 inch touchscreen monitor, at the upper part of the center console.
Used a motherboard from a very small formfactor computer, laptop components. Went through several different motherboards/CPU systems but none were top-of-the line.
Computer was housed in the compartment under the steering wheel, made a wood veneer panel to kinda match the factory woodgrain
Dedicated power control unit to handle startup and shutdown (adjustable delay after car shut off)
A keyboard in the driver's visor
Eventually put a trackball in the shift handle
Replaced the rooftop antenna with a unit that took in GPS, WiFi, and GPS (still using that antenna today)

Dedicated frontend software specifically designed for CarPC installs
Ran laptop based GPS software
Played MP3s so I didn't have to worry about a giant binder of CDs (remember those).

Was really fun to put together and actually have it work. People would wig-out over the ability to watch videos in the car.

I let the system lapse to the point of non-functionality of aging computer components.

Now I have an android headunit that does all of that for a fraction of the cost. Like your plans, I use it to display my VEMS data as well.

I think you can definitely make the space over the glove box usable for mounting a tablet.

I hear ya, and now you're making me nervous about making sure the specs are all right.

I'll be sharing my outcome once I have it printed.

Definitely orient it so that it's laying face-down. That way you don't need to waste time printing supports for the big open spaces. The printer I have access to doesn't have a build plate big enough for the whole thing so that is why it's in components. For me, each one is about a 10-12hr print. I will then glue each half together and sand/finish.
