VGA to stock NAV RGBs/RGsB: research results and questions
I'm am thinking of linking my stock nav screen to the VGA output of my PC.
Why? Simply because there is no room to put a 7" touchscreen on my dashboard. No double din, or even single din kit for my car (Infiniti M35). Impossible. Here is a picture:
Many have linked a computer to the stock nav screen, but their solution lies in converting VGA to composite cable, which is not enough for me.
I've found a very expensive unit ($550) that links the computer to the nav through S-Video, which apparently is much better than composite:
Will the difference between composite and S-video justify the higher price? I'm not very interested in playing dvds really, although that is nice, a composite cable would be fine for that stock screen. What I want is a good computer functionality, with text as sharp and crisp as provided by the stock nav unit. If the manufacturer can do it, why can't we?
I also found this, which is half of the price, but it comes with two composites AND a NAV IN input, which is RGBs or RGsB, don't know exactly which. Now can I link RGB nav in to my VGA computer?
Some more details:
Here is the 6 page manual with good pictures of the wiring:
This unit has the following inputs:
NAVI IN RGB Video Input: to allow the addition of an aftermarket navigation unit that has an RGB output
Now the NAV input I take will go directly to the stock screen, and it is RGB with composite sync (H+V), as you can see in the link above. NAVin = blue, green, red, sync, ground.
Now I need to convert AND scale my computer monitor to make it work, right?
Searching on this forum, I've found a lot of dead threads, and no one aparently did it.
Some solutions I've found:
This one says that it can "Can output a composite, S-video or RGB output at the standard 15K video signal", so it is not only converting (like this: http://cgi.ebay.com/Video-Adapter-S-...sid=p1638.m118), but also scaling. Is it really?
This would be great to use with the vga out of a laptop. But does this work?
Before somebody tells me to do a search, I can tell you, save your time, nobody has any of the solution above working, at least, didn't say so, or posted about it.
If this is the only solution, well, I'd have to say goodbye to a laptop, a macmini or even any small form factor pc. No low profile PCI card, means a big computer on the trunk...
Still, does it work?
Found on this thread:
But according to BassbinDevil user: "The Extron box runs off 120 volts, but maybe it can be modified for 12V.
Now, from what I can tell they only convert sync: they DON'T convert the scan rates. So, if the stock NAV screen runs at TV 15.75 kHz scan rates, this won't help you connect up a VGA source. Scalers do convert scan rates, and they're much more expensive."
Also, the PSOne thread (http://www.mp3car.com/vbulletin/lcd-...tronger-2.html) is not really useful to me, I think, because the thread starter was using already outdated 2003 cards that could produce 15KHz signals. Correct me if I'm wrong.
I hope this thread is relevant, but I really would like to know more updated info, and specially builds about the things mentioned in the many threads I visited.
Well, thanks anyway for any input.
