Next Project: GT-R MFD on 370 (oil temp/pressure, boost, etc...)

MotorvateDIY

A while ago, I came across a video that shows a Murano with the GT-Rs MFD (multi-function display)... and that got me going down another rabbit hole



^^^ Notice the" ***"? That indicates a missing sensor/CAN bus data.

As it turns out, the 2010+ NAV units (aka AV control unit) runs the same software and are configured for Nissan vehicles (except GT-R), Infiniti vehicles or GT-R. (with GT-R logo start up screen)

AND there is an undocumented serial terminal (12v UART @ 9600) at the back of the AV unit that can be used to read/write the configuration.

I have purchased an AV unti from ebay and it should be here in a few weeks.

When it arrives:
•I will clone the NAV disk drive. Having a back up copy may be helpful if the NAV drives start to fail in the future and if I mess up, I can put it back to the original config.

• Connect to the serial terminal and see what is available and version number.
• Config it to display the MFD
• Send CAN bus data to the gauges and see if/how they respond

Now, the GT-R has sensors that the G37/370 doesn't (like engine oil pressure, trans oil temp, etc) BUT a "analog sensor to CAN bus module" should work to put the required data on the CAN bus.

Anyways, that's the project goals.
