i know aobut the lilliput 7 in screen, but i've been hearing horror stories about the glare on it. is there any other suggestions for smaller screens or better? it has to accept a input from computer
or. if you know a unit that'll take computer analog and switch to the AVI cord type, that'd work too.

You mean VGA to RCA video converter, right? This is a vewry basic, cable in the computer field. Off the top of my head Steren makes a 3 way VGA to RCA cable model 253-512IV. You can get this for less than $14. the mp3car.com website makes me laugh sometimes but good info most of the time (they got a lot of car audio knowledge but not too much PC hardware knowledge). ------------- (1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).

To use that cable the video card has to be capable of using vga out to an ntsc signal. Most or some cannot do that

joesmith96 - YEAH RIGHT, 98% of the video cards can do this. maglin- get a cheapo vid card with video out. $20 at www.pricewatch.com can get you ant 8MB car with TV out. ------------- (1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).

but, and i'm not here to argue, but i heard those video out ports on most video cards put out really crappy TV signals.
i'm trying to keep the entire unit low profile anways, so a board with build in video is prime... now i've seen mother boards with built in video out, but again to my original point. i've seen these things put out excellent signals when you full screen the video in a media player, but aside from that, they were less than impressive.
... i need to do some shopping, but i'm not really sure what i should look for. i HAVE that 8mb vid card right here... and its the one that i was originally speaking of.... for some reason my 64 $ *at the time* GeForce 4 card's vid out refused to work... lol.
... thanks for the input guys.

I only speak from experience and can tell you that 99.99999999% vid cards even the $20 put out a nice RCA video signal. Now it seems like you may have some driver issue with your Nvidia card possible or a defective product. Again I only have about 6 years of real working (plus several years of working on PCs on my own) experiecne and I'm currentley a Helpdesk Manager so I definetley know what I'm talking about (not upset and not trying to brag just stating the facts) Get an ATI Radeon 900 64MB with tv out for $35 from pricewatch.com (free shipping). I think $35 is nice price and this is a nice older card. ------------- (1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).

I agree completely about the MP3car website....not too much on the hardware knowledge. Either that or the newbie responses dilute the real info as everybody over there are looking for something for nothing.
As for the video question...DON'T waste your money on the cheap fix. The display will suffer and you'll regret it. Currently I have my imobile system hooked up to my factory display using a little known Radio Shack part:
https://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5fid=25-3085
They stock a unit called the Ultimate XP Pro. It's a high-quality, extremely-tweakable interface that when couple with the right wiring it converts VGA directly to RGB (for factory navigation or aftermarket displays), Composite video, and S-Video.
It's highly recommended.

Carfreaknyc - Not sure what you mean by cheap fix. But I'll say this. Every regional LAN party I've been to has had 15-20 PCs hooked up to TVs via video out from the video card (most on RCA). I have 2 PCs one is outputing video from the TV tuner card via the video output on the video card (RCA) (it is an older Radeon 8500 which you can get now for $25). The other system also has a TV tuner card + a Radeon x800 Platium Edition vid card. which outputs to a 24 inch DELL LCD (12 ms) across DVI (so all digital here). I cannot tell the difference when playing movies, or working in Windows. I've had 2 friends look and tell me which one looks better, they could not see any difference, both images were life like and crisp. ------------- (1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).

A composite video screen CAN NOT produce the resolution required for a good picture. You will not be able to read text hardly at all. The lilliput and xenarc are your best options here. Try to mount it where the glare won't effect it. Mine isn't bad at all. ------------- Nik

I guess I should qualify what I meant by the display. I use the factory as a secondary monitor to my original Xenarc 800TSV. Yes, the composite video source for standard text piped to the OEM display makes normal text unreadable but as the iMobile GUI has larger text it is 100% legible. (So I use the factory nav for the entertainment value of the iMobile software). As for the cheap fix it was more of a general statement encompassing the entire Car PC project especially when using a VIA-based board versus an Intel-based board just because they come standard with the S-Video and composite outputs. An interesting read..... https://www.tolly.com/TS/2003/Intel%20Corp/CPU%20Testing%20Intel%20Low%20Voltage%20Celeron%20processors/TollyTS203124IntelCeleronSept2003.pdf -------------

I read the article and it is all about performance, nothing about the s-video or composite. The stuff they talk about is way dated (3 years +) (not to say that it is not enough for a GPS/ in car multimedia system). If I was to run an OS in a car system it would be Knoppix (knoppix.net), this is Linux modified Kernel. Let me give you an idea of how good it is on boot up times: You can run this from a bootable CD without installing it on the hard drive. I tested this on a Pentium M 1.6GHz HO notebook. From the CD it booted up, autoconfigured, NIC, VIDEO, TCP/IP in 1.20 minutes (without me even installing a driver). This is the compared to Windows XP install which is 35-45 minutes. This is a speed advantage of 35 to 40 times. Install Knoppix on the HD and you can boot this in under 10 seconds and as low as 3 or 4 seconds if you know what your're doing with the tweaks. The fastest I hear XP booting was 15 seconds, event hibernate is not that much faster/ There are a lot of apps for Knoppix (it comes with DVD player, MP3 standard). You can also load Knnopix to RAM (you need about 512MB but memory is dirt cheap for mainstream). You are now running the OS from RAM which blows away hard drive speed. There are also remastered Live CDs people made of Knoppix to stream line it and make it faster and bootup faster but still have the apps you want (check www.knoppix.net forums). https://www.livecdlist.com/wiki/index.php/SLAX has a Slackware based version which takes 200MB to install. www.puppylinux.com has a 60mb install and includes DVD, MP3 palyer, web browser, spreadhseet programs and many more apps. As far as GPS https://www.gpsdrive.cc/index.shtml has a awesome program already developed for Linux And there is a great array of other GPS features here: https://www.knoppix.net/wiki/Main_Page ------------- (1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).

impressive posts guys. highly appreciated input. that unit by radio shack supports 1600x1200 resolutions... now that is beauty in a silicon chip. lol.
anyways, i do appreciate the posts. see you all on the flip side.

Dated??? The chipset hadn't evolved since then and the data is whetstone type benchmarking standards.... The Xenarc Celeron 2.0GHz box smokes it. And as for the GPS/Multimedia part I made no claim of that specifically just that when you put it on a slow box you can infer the performance you'll expect. After all check out how long it takes to open Word or the like. Although I do agree on the Linux solutions and they will perform better since the gawky overhead that's consumed by XP services and resources are eliminated.

Bro it is date technology. I have currentley a Pentium M (the one you normally run in a notebook) @ 2Ghz. which runs whtestone and 3DMark 2K5 at the leve of a Athon 64 3500 in a mini desktop. Power consumption is really low (25 % of the power a P4 1.6 Ghz normally takes). Let me know when your Xenarc Celeron can hit the levels of a Pentium M 2Ghz. ------------- (1) Kenwood Excelon Head Unit KDC-X589 (24 bit Burr Brown DAC, 3 X 4 volt RCA).
