Ahh sorry to hear it didnt go as planned. Why does the car shut down the computer? I dont see how this could effect it? Is the computer not just hooked up to the battery? What about running linux ?

I don't think the problem lies with Windows 7 - check the wattage being supplied by whatever converter / PSU you're using to power the PC - if the wattage isn't up to par, the PC will experience stability issues similar to what you're seeing.

That being said, there are Linux distro's developed specifically for carputer applications - so that might be a better bet.


Me, I'd have just used a Raspberry Pi, a touch-screen with USB and HDMI, and called it a day... might not be the fastest thing around, but certainly beats the whole shebang of building a dedicated PC.

Either way - kudo's to you for the effort sourcing all the bits. Should be nice once it's done.

It is actually supposed to turn it of, its windows 7 that's being a itch..

What happens is that after 30 secs the computer hibernates and then after 2 hours it shuts the computer down so it doesn't drain the battery, this is a function of the power supply (Can be changed to any times you need).

The thing about windows 7 is that after a couple of shutdowns that's not done by clicking on shutdown from the OS, it goes into start-up recovery.

I have now Installed windows 8 (super fast boot up, and touch friendly) and will be installing the computer into the 330 instead of the 318 (never drive it anymore).

I am also planning to install the computer in-front instead of the back.

I have also now ordered ibus interface cables to control the windows from the computer.

I would love to see this, have you made a thread?

So the new case arrived today, the pic attached shows the old case on the left, new case in middle, and a normal dvd writer for size comparison.

The pic of the cable is the ibus cable which I will control the windows with and make the steering controls work.


Will pickup the GPS unit on saterday, and tv card / radio on Tuesday.

The last pic is the dstv unit

What program u gonna use with the ibus cable?

The frontend software does hav3 plugins for the ibus interface.

But I was thinking to dev a small program that works on sequence remove clicks, for example if I unlock 3 times real fast that the driver window rolls down auto without holding in any button ect. And 4 for all and so forth

The frontend will be ride runner, and new os is win8

I have read allot about navcoder, will have a look at it as well.

Once I find a answer about how to hook up an aftermarket headunit to the BMW HiFi Loudspeaker system, I will be installing the computer, I have everything to make it brilliant now.

So I have loads of time on my hands lately, so will finish the project in the next week or 2.

I manage to test fit the new casing in the dash but was still little bit too big for my liking, so I modified the casing to fit properly which it does now, I have all the stuff I want to fit now, will just go out and by the cam on the weekend and just waiting for the new relocation unit to fit the 16mm buttons, will buy the 4x45w amp chip tomorrow and begin the custom DIY amp, the big ass amp I bought originally worked, but too big too fit the dash.

All that I still need is the following:

  1. Card reader that's small enough to fit ashtray, will fabricate this in there
  2. Rear view camera
  3. Custom amp

So the previous amps I posted yesterday aren't going to work, turns out they need dual x2 power supplying 12vac @50watts each. So a no go, because I do not want to add transformers and making it bigger than it should be.

I have sent my minions to get me some new ic's today, I will be using 2x tda 7297 chips.

Will post the progress tonight.

Thus far the harness is completed, will post pics tonight, so once the amps are done it's just fitting the computer to the car, which will take no more than 1.5 hours, Total wiring is not even more than 1 meter, previous version of this used over 60m cabling.

All that's left is the ashtray mod, but I will fit the computer if that's done or not, and will just add it later on, but ifI am lucky I will find all the parts the weekend and do it then.

so I scarped the idea of building the amp myself, the sound just wasn't what I wanted.

I test fitted the "new" design yesterday and must say I am impressed by myself to have managed to fit the whole computer with 2 hdd to the dash.

I had a small problem where there wasn't any sound to the carputer, it turned out that the blue remote wire isn't for sending signal from the car to amps, but it is actually to send a signal to the OEM amp :flyfun:

Here are the pics of the carputer in test fitting the mobo, psu and LCD bord. Will upload some more tonight when everything is nicely tightened, sorry for the bad quality, forgot to turn the flash on.

PS: It's upside down.

And this is the amp I ended up using,

Looks great man. I'm just curious. Have you tested in a heated environment? Those PC's have quite high tolerance to heat but if it is running in an enclosed space at 40+ degrees it might give problems...

Only while it was in the boot, but I am aiming to get it done tonight or tomorrow night, I will then check and decide what to do from there if it doesn't handle the heat well. I mostly drive with my aircon on in summer so I guess the vents right above it should keep it cool enought.
