One relay for the video should do it for me. I have the navtool unit that has a switch to switch the ipod. The only thing that I need to control with the relay is to switch between the normally closed stock nav unit and the normally open carpc.

I figured out that one of the main problems that I was having was improper grounding of the rgbs coax cables, that caused the screen to be scrambled. Now, after fixing the grounding problem I can see the computer screen when the relay switch is fired up but the screen is wavy, it has a small black line on the left side and the whole screen is wavy. I haven't messed with powerstrip yet to set up the refresh rate. I'm hoping that is my problem.

My setup goes like this, stock unit into navtool, navtool harness gets spliced before reconnecting with the wires to the screen. The splice is where the relay is connected and where the switching from stock to pc occurs. One of these days when I'm not lazy I'll draw up a diagram incase anyone else wants to do the same setup.

 

Power strip was the fix for me. Ill post up later what my settings are.

 

Ok so here is another question: I only want to connect my CarPC from the Scan Convertor. So....is there anyway to purchase just the wiring harness from a navtool etc so that I can create a splice that is plug and play vs cutting into the stock harness.

Thanks again!

 

WOW....you are a geniuss!!!! PROPSSS

 

Sorry for the late reply but yes you can purchase just the harness from doms unit

wrxboy, could you post up your power strip settings? I think that would help me out. Right now I'm fighting w/ my wiring and scan converter. I am not getting any red, just blue and green. I have to get out there with my multimeter but i've been way too busy lately. If u could post up your setting it would be a huge help.

(and p.s. you're a huge help on this site and one of the reasons why it's a freaking awesome forum, thanks again.)

 

so how much do you want to do this to my 07 TL type-s? this is one sick setup, i'd be willing to spend the money to get it!

 

The newest update: I have video! (kinda)... it's not scrambled any more. I was trying to power my scan converter from the usb line out of my netbook.... although on paper this should work, it should be 5V approx. 1 amp -- though it may have been less than 1 amp-- this was the main problem. The video was scrambled (probably underpowered) when going off of the netbook, with a ac/dc adapter it works fine. I thought that I tried this long ago, but oh well. Now I'm just not getting a red signal (I'm sure it's my wiring). So I have to take the relay out again, fix the red, and then I'm good to go!

 

Ok... so i fixed the red wiring... Now I get a signal from that wire.... but I do not actually get red. The colors are all screwed up. I get blue just fine, the green is gray, and the red is orange. Bad scan converter? Still the wiring? I plan on buying another scan converter with the hopes that will finally fix my problem.

 

hey guys. Ok so I'm not new to the car game, but I am new in my 04 TL! I have many mods started already but i am very interested in this carputer thing! I am changing out to the 08 factory nav setup soon. I want to use the 4 wire touchscreen usb controller, but I was wondering if anyone knew what wires I would need to tap into on the factory screen to interphase to the controller. And I suppose that these have to be relay driven as well to switch from controlling nav to controlling computer.

Thanks in advance for helping this TL newbie out!

 

I'm not sure why all the pictures were deleted from acurazine, but there used to be some pretty good pictures on this thread showing which wires. The 08 nav setup might be different, but for my 07 screen the wires are at the very top of the screen. When you pull off the back cover of the screen you'll see a ribbon cable at the very top (4 wire) and this is the cable that you need. The cable is inseparable from the screen and attaches to a connector on the board. The signals out from this cable are untouched resistive signals from the screen. The parts list on the first couple of pages gives the ribbon cables and connectors needed. I can't find any of the actual photos, but we'll see if this works:



as you can see the cable is very short. Good luck!

 

Where are the pics? why were pics deleted? they will be very helpful for noobs

 

Is there is any installer or anyone who can help in install carputer near LOS ANGELES, CA. i would even help him out if he wishes to charge for his skills. i have 06 tl and i need to know what things are needed which are updated.

 

Hey guys,
I know this thread has been around a while and is mostly dead. Sorry about the missing photos on the first post. I canceled my hosting account where all the images were located. I think I have a backup of all the images somewhere. Give me a little while and I will dig them up and post them somewhere else so others can still benefit from this thread.

Also, I'm planning to sell my TL soon and will most likely remove the computer and all the associated components, unless I can find someone interested in the whole package (car with carpc). Anyway, if I do end up removing it, are there any requests for photos as I go to show more detail of how I did this mod?

If I remove it all, I'll probably try to sell the whole setup, computer, relays, cables, cd-drive, usb hubs, etc. Everything. Hopefully someone will be interested.

Mike

 

Did you ever end up finding those pics again? I just found your thread and find it well put together just wish I could see pics of the interface. Did you end up selling the carpc?

 

Unfortunately I wasn't able to find the pictures that are missing from the thread. If I ever dig them up, I will be sure to post them here.

I sold the car, but I still have the carpc with all of the associated wiring, parts, etc for a full install. It's not exactly "plug and play" since you need to tap into the factory signals for the navigation display as well as power.

It's for sale if you're interested. Let me know via PM and I can take some photos and come up with a price for the entire setup.

 

i wanna upgrade from non navi to navi cuz this car pc. do you install this in chicago area? how much would you charge?

 

it's amazing if any of you repost the pics, it could be better if someone repost the diy.

 

every one saiy its simply, but w/o the pic how can i do it, can anyone post some pics or redo this mod for our 3G?

 

Here is a link to many of the old photos that were hosted on my webhosting account that is no longer active. Hopefully this will help anyone still thinking about performing this mod.
