HVAC/Radio/Nav Control Issue

gurneyeagle

I've got one of those "intermittent" problems that until it becomes a regular occurrence, I'm just going to have to live with unless someone knows what's going on. There is no point in going to the dealer until I can replicate the problem there.

Here's what's going on - every now and then, I lose all control for the radio, HVAC and nav. The steering wheel controls still work though.

When it happens, none of the buttons or knobs in the center stack work. To correct the problem, I simply have to turn-off and then re-start the car.

Yesterday, the a/c decided to come on at full blast when it was 56*° outside!

I've done a search, and this is the only problem I found that is slightly similar to what I have going on:

2012 370z ST w/nav issues with Nav and climate control

Anyone else have a similar issue? Any way my nav by-pass switch could be the problem? I'll have to yank it before bringing the car to the dealer.

Thanks in advance.
