2011 G37S. Recently noticed I have some buttons not working. Anything dealing with the nav is out, and the settings button as well. Radio and a/c are fine. Can't check the diagnostic because the settings button is needed. Do I just need to replace the button assembly? It's only $10-$20 from LKQ on eBay. Or perhaps the vents with the button assembly as a whole would be easier to swap, less disassembly? Mainly I need to know if either will correct my problem. I don't use the nav but I do like to access my maintenance reminders and fuel mileage settings.

You could try checking the ribbon cable that connects the NAV switch assembly to the HVAC/Radio switch panel. Could be as simple as a loose connection.

With anything there is no 100% guarantee that replacing the switch assembly will resolve your issue, though more than likely it will.

Sounds like your control board is going bad

Ordered one from LKQ on eBay. Got a 90 day warranty. I'll find out this weekend.

Ordered the whole piece. Vents, trim and the buttons. Thought it would save a few steps. But my original trim and vents looked alot better than the replacement so I kept them. Problem is solved. Everything working again.

Glad you got it sorted and working again. Thanks for the update!
