Let me just clarify that I modified the stock LCD with a touchscreen.

I did post a few photos but none of the higher res ones with instructions.

It did involve cutting some metal and disassembling a good part of the LCD which some might be REALLY REALLY uncomfortable with. However the end result is a very flush touchpad overlay.

yunusyu

so you put in an aftermarket screen in....please tell us how
and that guide would be so useful

yunusyu

but the best way would be vga into the screen, with a touchscreen stuck in front of the screen

Man you kids seriously need to learn how to read.

I DISASEMBLED MY STOCK LCD AND MODDED IT TO FIT A TOUCHSCREEN OVERLAY. THEN SPLICED THE RGB+S CABLE FEEDING IT A 15KHZ HORIZONTAL / 30HZ VERTICAL INTERLACED FREQUENCY USING POWERSTRIP. I SWITCH BACK FROM NAV TO VGA USING A CHEAPO KVM WIRED TO A PUSH BUTTON SWITCH ON THE DASH ACTIVATING A PUSH-SOLENOID MOUNTED ON THE KVM UNIT.

Be patient, I will write up all of this.

http://www.converters.tv/assets/Vga%...cga.rgb_81.pdf
its says it converts vga to rgbs.
If i use this and then have powerstrip send a 15 by 30 hz, it should work..i think...

I wil try to organize everything else you said anichristpm...and get back wiht a layout
sorry i am a noob at the stock screen hacking

yunusyu

Thank you so much for all your help...

[/ps]And all i am waiting for is some help on how to correctly attach a touchscreen. If i dont find any... I will dive in and try to overcome any problems as they arise.[/ps]

here it is:

truemagellen

you don't just splice the sync together...if I recall...antichristpm help

antichristpm

i'm really stoned and tired right now i'll look tomorrow but i think this man has got a possibility... however i think the only output at 30hz was at CGA res which if i remember correctly is only 320x200... i'll do a lil research tomorrow, email them etc...

for that price though it's golden.

Okay, to once again point out that folks don't read...

Here is your much cheaper answer to all: http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW

I picked one up for $1.50, you take pins 2,3,5, and 9 for your RGB+S as per this diagram and ground 1,6,11,13 and 15. http://pinouts.ru/data/pin_MacVideo.shtml

bump for a 6 month old thread...

Is powerstrip absolutely necessary for this particular mod? or is there a way to hack the h- and v-syncs down from 60hz to where they need to be, by using hardware alone? I dont think my laptop has the capability to do custom timings

truemagellen

we can restart this discussion yes...a good idea

really unless you buy a converter for VGA or component video to RGBs which costs well over $500 you are looking at using Powerstrip...which is a great program by the way.

I'd explore more but it will have to be in a week...we can discuss it if you want over AIM too if that is better

antichristpm

Don't forget certain video chipsets won't go as low as needed [in regards to frequency].

I've been searching for a way to interface a laptop with the Nav lcd screen. This old thread appears to be the best one I've found on the subject, but there isn't quite enough concrete detail.

From what I understand, the wiring from the nav dvd to the lcd supports rgb + a sync signal that has botht he horizontal and vertical synchronization signals. What happens if you feed RGB and a full composite signal? Will the lcd pick up the H/V or will there be too much noise. The reason I ask is because I saw an XBox cable which has RGB + Composite video: http://www.xbox.com/en-US/hardware/x...60svideocable/

Would this solve the issue of having to build my own circuit to merge the signals?

Alternatively, if I want to use a laptop for my carputer, can I bypass the vga and simply run signals from the built-in LCD?
