Provisionally, I’m using the LG 5 ľ DVD-RW drive (SWA 4446b), but this is temporary, it’s just for installing apps and making HD clones. I won’t need a DVD writer in the trunk, I guess.
DSATX 230W DC-DC PSU with serial controller
Case: Antec Aria NSK-1300
Garmin GPS 18 (I bought years ago, was unused since my other car has stock nav and I used an aftermarket Mio 380 (for sale) on this M.)
Space Navigator with these drivers.
Turtle Beach Audio Advantage Roadie 5.1 USB soundcard (optional, don’t know if I should use it)
OBDPRos OBD II Scan tool USB w/ right angle connector
I nlited an XP Professional SP3 (nLite 1.4.1), not so much to keep it small as I have plenty of space and memory to deal with XP, but to try to make it boot and run faster. I changed the boot screen to this one and I’ll later start my front end as a shell and will try to use minLogon to speed up boot times.
At first I tried to hack the connections between the AV Unit (Nav Unit with those with Navigation) and the stock 7” LCD screen. I have already installed the 4PDT relay in place to allow me to remotely switch between the stock data and my computer display. The problem is of course to emulate the RGB+sync signals the car display is expecting to get. This is the thread.
There are some products in the market that use Composite inputs as source (TV and nav to go, PAC, Gnet, AvElectronic), but although these might be good enough for DVD playing, it is far from good enough for a computer display. The stock 7” widescreen LCD has 16 bit depth color and (as I can see in my FX35 with nav) can display the small font on the navigation maps reasonably good.
We have to find a way to convert the computer’s 30KHz VGA (RGB with separate Horizontal and Vertical Sync) output into Arcade/CGA style 15KHz RGB+combined sync inputs required by the stock screen. I have tried the Australian made Converters.tv VGA to CGA Converter, with not much success. I also tried the ArcadeVGA from the Ultimarc, from Britain. It also failed to deliver.
As I noted at the last post on the thread mentioned above: “It seems that indeed my car is unique in that the display does require a rage of .4 to -.4Volts for the video signal. This also goes for the 2008 G37s, and the 2007 G35: it also requires this unique negative signal level. Idem for the 2006 G35. […] The 2005 G35, though, wants RGB signal level between 0 and .8. I also checked the 2007 FX35 service manual and, although externally the screen looks about the same, the signal levels are much more standard, 0 to 1 Volt. So the 2005 Gs and the FXs all share the same screen, but for some reason Infiniti "upgraded" the others.”
