So, my new 2004 Freelander is coming on Thursday, and I am looking into building a carputer in hopes of adding mp3, DVD, divx, and GPS capabilities.
Firstly, I was wondering if anyone knew of existing Freelander projects that I could look at for inspiration/guidance. I donít know very much about the stock radio that it is coming with, but I donít think it will have any auxiliary ports. In this case what would I do to wire my system?
Second, reading through many of the posts I am still a bit confused on powering the system. I would have the computer, which I think I will get a micro or mini ATX system (whichever is smaller) and the screen, maybe a Lilliput 619GL-70NP (I saw it online for $279 which is the best price I have seen for a 7" touch screen)? Anyway, how will I wire the whole thing? I have heard bad things about inverters and good things about this opus PSU. I donít really know all the benefits of the opus. I donít want to be wiring anything to a battery so I would want something to the cigarette lighter. In this case how would I wire both the computer and the screen?
To wire the audio to your stock speaker system, your best choice would be get an aux input adaptor for your stereo. A couple places make these, you'll have to check with them to see if your car is supported. They are PAC audio and Blitzsafe, just google and you'll find them. If they dont have what you need, you'll have to replace the radio, get an FM modulator, or get a tape adaptor.
To power the system, if you get the OPUS, you should wire the power line directly to your battery and the ground to your car's chasis. The third line gets hooked up to your aux line. Search and you shall find about 10 million more posts on how to wire up the OPUS or an inverter. Do NOT wire the OPUS or an inverter directly into the cigarette lighter port, the wire guage is not rated for that kind of amperage. The lilliput you can plug directly into the cigarete lighter or purchase a cigarette lighter socket from radio shack and wire that directly into your existing cigarette lighter, then hide both the socket and wires for the lilliput this way you won't have to cut the power line to the lilliput and can use the existing fuse in the lilliput power line.
Thank you for the response. I was wondering which 7 inch touch screen is best?
Hello Nibix, I didn't complete my carputer yet (wainting for some of the parts to arrive), but I hope I can help with a couple of tips (based on my setup). It is STRONGLY recommended that you wire the computer straight from your battery with an in-line fuse, just like god_of_cpu said. My suggestion is you go for the Opus 150W. That's the best PSU from what I've read, and you won't have to wory about ITPS, shutt down controllers and stuff like that(150W was my choise). For the screen I'm going with the 7" Lilliput (I want to power it from a 12V rail from the PSU, so that it turns on when my carputer turns on). I choosed it because it was the cheapest, although it seems to have a lot of issues.
I would'n recommed using the stock stereo. The sound isn't great whether you use an FM modulator or a tape adapter (I've had both). I have an USB Sound Blaster Audigy NX2 that will plug into 2 amps(a 2 channel for the sub and a 4 channel for the front and rear speeakers). From what I've read from the people that have the sound directly to the amp, this setup has the best sound quality.
I hope this helps a little. If it doesn't than I'm sorry for the long thread.
Thanks Cris that info was helpful. Now that I have the car the issue is where to store all of the components (most specifically the display). I will take some pictures as well as measurements, so that I can get some good advice.
I took measurements, and I found that the factory radio (head unit) measures 7.5Ē horizontal by 5Ē vertical. Would this be enough to house a touch screen? Would I have some room left over for adding a slot loading laptop sized dvd drive?
Here are some pictures to give you an idea of what I am working with:
The house of the Lilliput measures 4.84" to be exact, and a slim drive about 0.5". So, in theory, it woud'n be enough room for both the screen and the slim drive. However, if you plan to make a custom dash(to look stock), you could place the buttons of the screen to another location (I've seen this done), and thus creating space for the slim drive.
Here's a pic of what you want in your car(without the slim drive). And by the way that's a very very nice car.May it bring you lots of satisfactions.
If you send me a larger picture I can make you a nicer one.
