2007 TL-S. The auto-dimming option on my navigation stopped working recently, which makes it difficult to use at night. Can still switch manually between day and night. Auto-On control still works for my headlights, which makes me think it’s a software issue?

thoughts/suggestions??

 

Is your instrument cluster back lighting set to max brightness?

 

turn on headlights and press the minus (-) on your gauge cluster brightness 1x and it'll fix it.

 

That was it. Thank you!
