I have an 06 G35x Sedan- radio does not work plus [Heat and Air[/LIST]Air problems I know it is the Sensor Board but can not find one. Does anyone know the part number is and where I can get one besides Japan. I heard there a lot of them out there with same problem.

Part 18

To verify you can call and have them check your VIN number but that will give you an exact part number, then you can search the internet properly.

EDIT: I assume this is what you mean by "sensor board".
