Its a little more complicated. The dvd player once its engaged will play music through it and you can not play your music or listen to anything else other than the dvd player. You will also have to have the video play hack when you are moving, but then that disengages the navigation.

oh yea completely forgot about the sound issue there. so the back up camera seems like the best option at this point.

Let me shed some light on this situation. After many hours of research, I figured out that Infiniti and Nissan have switched to a new video interface called GVIF. GVIF stands for Gigabit Video InterFace.

This interface takes regular video signal (red, green, blue, hsyn, vsync) and combines it into a digital serial signal which transferred over 2 wires. This is what the factory service manual referred to as digital RGB. Once the LCD receives this signal, it has another chip to unscramble the signal back to rgb+sync.

Fortunately, this technology has been in use by Rangerover and Toyota for a number of years already. Thus, there are some products available to convert to this signal. The only one that would work for us is this:

GVIF Interface for Lexus/Toyota/Land Rover/Cadillac/Jaguar - Video Interfaces - Multimedia Interfaces - CarSolutions Online Shop

This allows you to add 3 composite video signals to the factory screen. The only problem is that they do not have a cable yet for Infiniti/Nissan. So you would need to cut the factory cable.

Thanks for the great info Modme, I will be looking into this. The site also says "GVIF Video Interface for Nissan Soon in Stock". I sent them an Email asking if they are almost ready.

Great research Modme. Thanks for doing this!

UPDATE EDIT: Well after talking with the company that makes the GVIF, they said the GVIF that is for the toyota/etc doesnt work very well on the infinitis 2010+ and that they are working on a new interface that should be out in September and will also include cables 2010+ Infiniti models.

Modme I hope your ok with the little hijack of your thread toward this 2010 interface issue. We can make another thread if you like to keep your clear of this?

Nah, this is good. My old system has been ripped out. I've upgraded my navigation system and screen to the 2010 version. That is why I am also very interested in the new system. I also contacted the website. The interface for NIssan/Infiniti is ready. The interface itself is the same as the Toyota/Range Rovers, we just need the cable for Nissan.

According to my contact, the box and cable is ready for purchasing. He agreed to give me a good group discount for 6+ units. I started a group bu here:

So this would only work with a 2010 LCD, right? Which in turn would require a 2010 A/V module?

Any chance on a writeup on how to swap the 08-09 for 10+ system, or at least a few part numbers?

Did you get rid of your equipment for your old install then? I'm going to do this on my '09.

Hi modme.

Sorry to resurrect a long dead thread, but this is the most appropriate topic heading.

First of all congratulations on pioneering the Scan Do solution. The 15kHz discovery was certainly a crucial break thru. I have just purchased a non-working Scan Do 1024 on eBay and am in the process of getting a working one. I have also purchased some latching and non latching relays as well as a discreet flush mount activation switch and an Arduino Pro-Mini. My plan is to implement the schematic above but also to add an option to mute the audio when the GPS is talking, and of course the 'ol parking brake/VSS trickeroo all controlled by the Arduino interpreting button pushes. So I have some very specific questions, and I would appreciate if you could answer BEFORE I pull my dash apart, as I would like to do this only one time.

1) Can you please confirm that the USB Touch Screen Controller is SLT-TP05-USB?

2) Can you please provide the FFC Connector part number for 2008 G37 Touch Screen FFC?
(In other words, when you pull the stock FFC Touchscreen ribbon cable out of the display, what do you plug it into?)

3) Can you please provide the corresponding FFC Ribbon Cable Part number?

4) What are the native resolutions of the 2008 and 2010 screens?

5) How did your 2010 Screen upgrade work out? Would you recommend it over 2008?

6) I presume that if you already have 2008 Nav, then to upgrade to 2010 Nav you have to swap the screen unit, the AV Unit, and the connector wiring correct? Any other major components?

7) Where do you get the pigtails for 2010, and what are the part numbers?

8) I am using latching relays so that they "remember" and also so that I don't leave a relay coil powered all the time. What 4pdt relay part number did you use?

I will take pics as I build this, and report back to this Forum...if anyone is interested. Here is my preliminary design plan. Any comments or would you do anything differently?
