Lights Behind Buttons Surrounding MFD Don't Work

Hi Folks,

I *think* I may have a problem with the lights behind the buttons surrounding the Multi Function Display on my 2013 Prius (ex. "SEEK", "TRACK", "AUDIO", "SETUP", "CAR", etc.). The other night I parked the car and turned the headlights off for about 5 minutes (I generally leave the lights on at all times when the car is running - day and night). I turned the lights back on and when I did I noticed that the lights behind the buttons surrounding the MFD were no longer functioning (so you really can't see the buttons in the dark now). My wife tells me that they've always been like that, but that just doesn't make any sense to me (I'm almost positive they were working before I turned the lights on and off). About 2 and 1/2 months ago I installed an isimple gateway so I could hook up a SiriusXM xv200, but I wouldn't think I would get a problem like this from doing that 2.5 months after the fact. A couple of questions:

1. Should these buttons light up (or is my wife correct that I'm crazy)?

2. Could the problem be the isimple gateway?

3. Has anyone else experienced this problem? If so, do you have any recommendations?

Thanks so much in advance for any help you can provide,

David

 

I'm still under warranty and I have checked the dimmer switch (it's not that).
