Good man Thumbs Up

Iv not been in touch regarding the interface as the tossers have stopped replying to my emails ..they wanted me to sent my pc to Korea so they could investergate the issues !!! Shocked

But there was other things wrong with it too !!!

Were you getting your converter from ..that may be an option for me aswell Thumbs Up

I have a load of pics of dismantling the screen if you need any help when you get your parts ..although its quite straight forward.

Its an easy conversion ...just soldeing the fiddly little connectors that are the problem

United Kingdom 2014 Discovery 4 3.0 SDV6 HSE Lux Auto Causeway GreyDiscovery 4

Just looked on ebay:

http://cgi.ebay.co.uk/VGA-To-S-VIDEO-RCA-C...dZViewItem

but that's not the one I used before - but I can't remember the name of it, but used one for a client recently to convert the output from a server to composite to feed into a old cctv monitor. The image quality was ok but not very fine. I figure it would be fine for centifuge or whatever that was called (tried the demo - looked good) as it is big buttons and fints but not sure how good on say memory map. It seems the only option though.

I'll trawl the emails and web to try and remember what I bought - thought I saw it in CPC maybe, or was it some of the other IT trade stuff that drops through the front door everyday... Exclamation

Did you buy connectors for the ribbon cable or just the cable and the widget from america?

Anyone else watching this thread want to split the US postage costs and order a few of these interfaces for the usb touchscreen (then make the rest up as we go along!!) Laughing

Came back to me in the end....

The one I used before was a Grand Hand View from grandtek for about £40 . There are other products from them just not sure how well it will work on the small screen.

Touchscreen Alt/LR

Sturge/Wiggs,
magnificent to see such commitment. I have attempted to get just the surround through my dealer who said that this would not be a problem though it would cost just under 3K Question but as a bonus I would get a touchscreen and the other parts thrown in for free Laughing Bloody brilliant. Anyway I have sourced a complete display for a lot less then that and will be mucking around with it to get it to work.
My intention is to mount the computer under the rear middle seat for ease of access and also for lack of heating in that location but lots of air circulation. If you can think of a better location let me know as I was thinking that the USB GPS receiver could be mounted in a dummy antenna on the rear of the roof in the std location.
Project has to wait now until after I install second battery and get car ready for trip during school holidays 4700k in 17 days should be brilliant Very Happy
I will take notes, pictures and post once finished.

I'm from the otherside of the house, but am going to be adding a carputer. I love this idea, wana build me one for some $ ?

I'm thinkinng about taking this on but with the very small stuff it can be difficult for myself, I lost my hand in Iraq so it makes it difficult to do small electronic projects one handed.

what exactly is this part for? Has anyone else done this modification?

Where did you get the 4 pole double throw relay from?

Is this the strip board you used?

Thats just some help in identifiying the names of the connectors ...

Rs circuit board ...yes i used the same stuff ...please note that none of the small connectors line up with the holes in the board...i had to spred the terminals out to try and make them fit in the holes .You can get board with no holes and drill them yourself ..but very fiddly.

Rs do 4 pole double throw relays..something like this http://uk.rs-online.com/web/search/searchB...;R=4881825

I used a slightly smaller relay on mine:

As with the one wiggs suggests, it's a 4PCO one.

this one? I'm a novice with electronics, except for audio stuff.

http://uk.rs-online.com/web/search/searchB...oppingCart

Is there a specific type of solder I need?

Here is a more specific list for the next person who decides to take this on.

Did you buy the enclosure from them as well?


This enclusure comes with the custom fit board, http://www.serpac.com/products_s-111-111-i.htm

What are the dimesions of yours?
