    Regular Lcd to touch screen?

    I have a regular indash motorized lcd. Instead of buying a new touch screen, I was wondering if it is possible to converted to touch screen? and how difficult to convert it? I read some posts about touch kit, but not really sure is that what I need? my monitor made by Innovatek.
    Thanks in advance

    A touch kit is pretty simple to install IF you had the basic skill and knowledge to disassemble and reassemble your existing LCD.

    To install a touch kit like my friend Mobile and Solid sells you would take appart the screen. The next step is to remove the LCD from the bezel. Next, you put the touch overlay inside the bezel and put the LCD back in on top of the overlay.

    The touch screen becomes the meat in the sandwich. You use double sided 3M tape (the white kind) to affix the touch kit to the bezel and the foam creates a buffer between the bezel and touch kit to prevent false clicks from the bezel.

    From there it's just putting things back together and plugging the touch kit USB cable into your PCs usb port and installing the drivers.

    To be honest, the touch kit I installed in my screen has been better than the three Lilliput, Xenarc or DWW-700H screen I owned, hands down. Here is a thread about it:

    I will be posting pictures soon.

    Thank You for giving me such a very informative replied, very appreciated.
    I was wondering if the kit would fit inside this monitor, please see attachment.
    you also mention about vga to rca. how to find out on board video have tv capability?
    right now I have nvidia video card with tv out connect from svideo converted to rca adapter. video quality not that great, wondering how the quality of the adapter you mentioned compared to the one I have. I am planing to get rid of the video card so I can build smaller case so the pc could fit under the passenger seat.
    Thanks

    For starters, if that screen is a 7 inch screen (what the seller lists the screen size as) a 7 inc touch kit will fit. The kit itself will probably be slightly larger that the screen itself but will fit inside of your screen bezel.

    Why? Remember that the touch kits sit on top of the screen between the screen and bezel so it wont matter how big it is as long as it fits properly inside of the housing for the screen.

    As far as the VGA to RCA, my adapter is thing I picked up at CompUSA a little while ago. The resolution conversion sucks but thats because in RCA the refresh is not as fast as VGA. In general a screen that has RCA instead of VGA will require a much lower resolution in order for everything to be clearly visible.

    You can use the video card you have and just pickup a PCI Riser card which looks like this:

    Thanks for all the help. You guys are grrrreat! I just placed the order for the touch kit, vga adapter and 2.5" hd adapter, soon will be m2 atx psu (don't know this enough juice for Dell optiplex p4 2.8 pc?) as for vga adapter, I already have svideo to rca adapter, not too happy with it, I wanted to see which one is better.
    Thank You

    p/s I have a spare p3 800 small form, do you think I should get the p4 or use the p3? does it have enough power to run Roadrunner and other stuff?

    The key to your setup is a happy medium between processing power, power consuption, and memory required.

    You'll find that a newer P4 mobile chip will consume less power and perform far superiour to a older P3 chip. My suggestion is to plan out what you want to do. Remember, your highest taxing software will be watching DVDs followed next by using GPS.

    I don't use Road Runner so I can't vouch for it but I would suggest that you look into using a Windows XP based PE enviroment such as bartsPE to slim down the OS thus lowering the amount of resources used.

    Thanks for all the value inputs. as for psu, should stick with m2 or get something else. please suggest. Thanks

    p/s this is what I want to do, running dvd (usb version), gps street and strips, music, and radio (radioshark)

    The M2 packs 160w of power. That should be plenty to power your system.

    I was running a Turion 64 2GHz, standard 3.5 SATA drive, and tons of USB devices off the MP3Car PSU. You should be fine as long as you have a low power consumption PSU. There was at one time a guide on the forum for calculating the total power needed for your carPC. Search the forum and see what you can find!

    That's not good advice, and the M2 will not likely adequately power the system described. A 2.8ghz P4 is not a "low power consumption CPU".

    P4 CPUs take quite a bit of power on the 12V rail (I'm running a 2.4, and as I remember it's close to 70 watts (or 6A at 12V). If the OP is planning on running ANYTHING else off the 12V rail, then the M2 is NOT a good choice.

    You MUST look up the power consumption for your particular processor and attempt to calculate total power consumption per rail if you don't want a fried power supply unit. This is especially important if you are using the M2, because it can destroy connected components if it is overtaxed...there are multiple threads on this forum about that very thing happening.

    Thanks for all the input. I did check the psu calculator before posting. p4 at 2.8 required at least 86w, that leave me 10w left according to m2 specs (8A x 12v = 96w)
    That's why I am abit hesitate to place the order. Do you have any other suggestion.
    Thanks
