    Install/Power in dash LCD

    I've never done a radio install in a car and was thinking of buying an in dash LCD.

    http://www.digitalww.com/DWW-700H.htm

    Looking at the photos(http://www.digitalww.com/images/DWW-...losed_side.jpg) all I see is a USB(touchscreen) and some PS/2 looking wire coming out of the back of this thing which I believe connects to a included VGA cable..

    My question is how do I power this thing? I noticed other in-dashes(http://www.digitalww.com/images/DWW-K301_back.jpg) have a 2by3 molex-style connector w/ power, gnd, acc, etc.. I imagine this is standard for radios? and when i remove my radio there will be one of these connectors attached to my existing radio? Is this true, there being a standard 2x3 radio connector for power/gnd/acc/etc...? Ive seen/heard of wiring harnesses, will I have to get an adapter to convert from my cars wiring harness type to the in-dash lcd's type?

    Also when looking at the photos of the included wires(http://www.digitalww.com/images/DWW-...cessories.jpg), i only see VGA and and a couple RCA.

    I am very confused because the scriptions states it comes with usb, vga, video, and power wires.

    Oh and if I have a head unit AND the in-dash, and only one wiring harness... how do I get two harnesses?

    Thanks.

    Something's pluggin in there to power it.. http://www.digitalww.com/images/DWW-...ccessories.jpg

    See the small red wire at the bottom of the middle pack of wires? Wire that up to your +12v (preferrably regulated).

    So if that is the case, then I would not need two harnesses, but I would probably need a bigger PSU(I was going to get the m1-atx, which has 2A on the 12V rail).. I would be using a m10000, and a 3.5"HD. I think those alone push the 12V rail to its limit, no?

    ps. you got good eyes.. i stared at that pic for awhile and didnt see that red wire.. looks a little thin for a power wire.

    FYI

    I contacted digitalww about the LCD and they didnt have any further documentation online but they did confirm there is a PWR/ACC/GND/SAFETY wires.. The safety being a wire connected to the ebrake so that the monitor will not display if the car is moving.

    I requested getting the manual online.. we'll see if that happens. that'd be cool.

    I have that screen and it does not have a safety wire as far as I can see.

    Works nicely though.

    There is however 4 wires. Ground (black), 12v+ (red), ACCC (green i think) and another ground which is Blue if i remember corectly.

    Not exactly sure on why it has 2 ground wires listed, I can scan the booklet I have when I get home if you like ?

    Also why would you run this from regulated? Its built for use in a car so it should really be fine off the standard 12v power source. I mean I can understand a computer not being able to because its not built for the varying voltages but this is designed to fit in a din bay in a car, it has to be built for it.

    How do you have yours hooked up? Off a powersupply?

    I was thinking of hooking mine up to an accessory source, like the cigg lighter for a while (Hardwired behind the cigg lighter obviously). Will this work? I'm just worried about a power surge or spike and a smoking 700H

    And whats everyone take on an 'inline' fuse on the 12v red wire if I went this way?


    Later down the road I'm going to put a full PC in the trunk, but right now all I got is a screen, laptop and inverter Not the best setup I know, but it's all I got/can afford right now


    Hopefully hooking it up this afternoon, I'll try and get pic's up later after I do it for you guys

    Well most LCDs expect regulated power... I figured since this is in a DIN case it would expect a raw 12V from the battery, however it is so cheap I wouldnt be suprised if they didnt include a regulator in it.

    And that 2nd ground wire IS the safety wire. At least thats what digitalww told me. Somehow you connect it to your ebrake... Basically I think if it is not grounded then your monitor will not come on(i suppoose you can try it).

    Powering from the cig isnt a bad idea. I really really dont want to connect it to my PC PSU.. One because I dont want to run power from the PSU, and two because I dont want to put a 1A draw on the device which will already be running a 3.5" HD.

    good to hear it works well, i hadnt heard of anyone using it. cool. is the left/right tilt useful? thats why i think i'll like it more than the motorized w/ no left/right tilt.


    anything I should know about installation?
