i use different software, and there are lots of software available. depends solely on your hardware ...
i am going assembly for sale soon, real cheap deal, plug and play type ...

sourcing for cheaper parts in bundle and slimmer parts from overseas

the black box will be half the current size, slimmer solution for everyone, so
you could just locate it under the front passenger sit

plug cord in cigarette lighter place, then everything will be powered. (plug and play)
connect audio to the system, install "start" button ... complete .. hehe

bare with me, i will post the price in market place, try (really try) to lower under rm3K with everything
from car diagnosis, radio, reverse camera, gps navagation, softwares ... alot more,

for basic package will try to go down to around 2K or maybe lower
never know ... i try to price as low as possible and 5% profit (only)
so 1K only earn rm50, ahha ... i do for fun ...

well the price vary alot, depends what you want to use, like if i use normal nmea receiver and map king the navigation cost is around rm400
if i use sirf garmin with map will cost around rm600, so very hard to price. some need obd II scanner, some don't need.
but anyway, the software and console is standard, so ... i try to get as cheap as possible.

the best is not to modify the existing electrical circuit, just use plug in cigarette and do not and never connect your inverter to battery, even it is fused. .

TIPS for customiser:
CAUTION for rotary users, please install voltage stabilizer and regulator; encourage everyone else to do so.
DO NOT USE IGNITION START SYSTEM as power ON method, (UNLESS U HAVE A DELAY POWER UP CIRCUIT FOR UR DEVICE)
this will damage your alternator + batter + maybe starter.
All factory car like BMW doesn't run on PC, they run on customize board; so they did enormous power drop calculation,
know how to stabilize voltage, properly fused their gadget and .. etc
my fren car battery die and alternator damage because of this ... so lesson learnt, never never do that .

easiest is to install on/off button, let ur car start up, let voltage stabilize, then turn on ur gadget.

happy experiment. waiting for slim casing.
update soon.

tjay is correct, direct draw power from battery with fuse which is not part of the design usage. but if you draw from cigarette outlet, they expect and allow the usage from there, is safer that way, if you draw too much, your fuse in fuse box will burned, instead of your engine or other device.

use minimal power as possible.

i am waiting for slim casing from china, very slow respond from them and miss last month shipping.
If you don't mind you can purchase the ACER EL model slim pc ... running on atom 1.6, mine running atom 1.6 dual core ...
i can do everything else, like get the screen, software, elm ... etc for you, or u get i make everything work for u
abit slow on the EL model, but slim lor, if got money then can buy DELL slim desktop, very fast, but expensive

it is not embedded to the media player software, but you can run it behind it, the player will still play music ...
but a bit annoying when the navigator is running, because of the "words" is says, like turn left, keep left ... etc
u can buy Garmin receiver + software, looks nice, but expensive, mapking is the cheapest with normal gps receiver.

ODB scanner is around 80USD for one unit ... this is china made ELM 327 scanner, its emulate ELM chip it is not really ELM chipset.
it depends, if u use it in your car only, not diagnosis machine. get the USB or bluetooth ones ...
serial one usually expensive.

i bought it from butthead012 from lowyat net. ..
he is selling 900, i bought 880

nope, power supply comes with the casing, is similar to m2, m3 m4 ...
120W supply ...

why u want to mod the power supply , it already giv u power dy ?
i mean the PC already running at 240V AC 150 Watts, is normal for PC
and you just need a inverter to convert 12V DC to 240 AC

the cigarette is 12V DC output, so just need a inverter
just calculate who much power you will use in your car PC setup, i suggest 300 Watt inverter should be enough
the pc supply range is 120W - 150W for atom, some to 200W,
touch screen generally is around 8W + other this like GPS receiver + gadgets, like mine also calculated to include some
other mods, like LED dimer + digial gauges ... around 5 Watts

good inverter is around RM200, made in taiwan, if you want cheaper then can go from RM150 -180 made in china type
i think as long as it is put in the cabin should be ok.

hopes this help

OBD II from HK company Chemcern, you can get it from Ebay .. around USD 80 (includes shipping)
Yes, it works with centrafuse, depend on your vehicle.
so far it works on RX8, BMW E46, Nissan Skyline

well, make sure it is compatible with your car, as there are alot of version from ELM 323 to ELM 327
but it is cheap thou, good price. i bought usd 80 for mine, but they confirm it will work ... so i bought it.

bare in mine, these china made ELM 32X series, no longer working with new diagnosis machine.
only with the old one ... some program also no longer works with these chipset .

Added on June 10, 2009, 12:02 pmthe elm he posted is emulate chipset, not the real, well mine works with centrafuse, the rest i don't know.

there are few ways to do it ... it depends what hardware you have. what car your driving and what headset you using.

1. Run through you existing headset, this is the best, just plug ur pc out to your headset DIN.

2. Run through amps. three example you can run ... see the image below

first solution


2nd solution


3rd solution



OR if you using your original car audio as tuner without DIN, but want radio function back, you need this GROM
you can purchase the one that fits your car ... for new cars only. Basically it is digital decoder which utilize your existing audio system.
e.g. this is use in RX8 , GROM works with Centrafuse.

well i am not expert, but this is how i do it. ..

unless your computer running dc, then can ... most PC don't, unless you have special power supply
laptop diff, better check or it will fry ur pc

can, if you plan to just use 12V DC to 20V DC just to power you laptop using the cigarette plug ... no problem ...
i use inverter from 12DC to 240AC to power PC, touch screen, customize amp ... so very diff from your concept.

if you do that, most of the touch screen is 12V DC input or 240AC ... so you cannot use after you adapt it to 20V DC ...

hope this help ...

my wiring diagram - for reference only ...




hope this help ... this cover all necessary wiring, except AUDIO

the china motorised screen have problem with its resolution, it is not tune for PC output ... try to lower the resolution ...
your button or words might look big, but guarantee better viewing ... try 160x200 or 320x400

why not get a touch screen ? i bought one for my friend RM800 include delivery within Semenanjung

my screen is not motorized, is those with a stand ...
should fit in normal car 7" audio dock ...

yup, a screen with VGA port should have no problem with resolution problem

Very hard to find, plus cannot sync resolution with PC resolution.

i am going to open a new thread ... post link soon
