Greetings! I have a simple question pertaining to automobile Navigation systems. My Infiniti has a head unit that controls everything pretty much from HVAC to Navigation Radio, DVD etc. I have researched all the schematics etc and would like to upgrade my OEM screen to a higher resolution in preparation for adding an Android box in between the head unit and the screen. The current screen resolution is either 400x234 or 480x234 I am not 100% certain but it is definitely one of those. I would like to replace the LCD to a 800x480 screen. The OEM screen has a driver board that connects in between and takes the touch signal 4 wire resistive and the 50 pin RGB LCD and puts it on the system wiring and buss. What actually drives the resolution? Does the main head unit send out a 400x234 signal or is the RGB signal raw and the board on the LCD module interprets it and sends the correct timing and resolution to the LCD panel?
