The display screen in my iX is running disturbingly hot. Have had it for three months and driven about 4K miles. Today I happened to touch the back of the screen and was (very) surprised at the temp — and this was on a cloudy day with a temperature around 80 F.

It’s possible the screen has always run this hot and I just never noticed. Have others experienced this?

I have an Infrared based thermometer I can get a measurement from mine. How long does it have to be in Car Play mode before you notice it? I will take some measurements from the back of the screen and the front with both Car Play on and off and let you know what I see.

So I just took a bunch of measurements with my IR thermometer on both the front and back of the screen before engaging car play and after. Base temp was 72-75 F (which matched the temp in my garage) after starting the IX the screen (both front and back) never got about 79 degrees F. Interestingly the "Drivers side screen" both Front and back was a little warmer than the Navi/entertainment screen. I contribute this to the air conditioner vent that is located right behind the navigation screen.

I got the same measurements with and without Car Play running. I will keep my thermometer in the car and take some measurements on my next long drive around.

Yesterday I was driving for about six hours, using Car Play throughout. The back of the screen was very hot (can’t give a specific temp) for about the first two hours. For the rest of the drive it wasn’t particularly warm—slightly, but nothing that concerned me. The sun was not shining, and I can’t explain why the screen ran hot initially. All functions seemed normal throughout, no maybe no big deal.

No sorry, I would not know how to do that accurately, but its very hot to the touch
Hot at the rear isn't really that surprising. Though I don't know 100%, based on the panel specs I strongly suspect that the LCD panels come from Innolux Taiwan (INX). They have built a strong business supplying panels to automakers. Considering the pixel density of the two panels they are using, fact that an INX FFS panel has about a 9% transmissivity, and that they are likely using a direct matrixed LED backlit to get the desired front-of-screen luminance, they's going to be a lot of excess heat coming off that backlight.

The good news, is that the heat tolerance for the panel is extremely high and this shouldn't be an issue.

I'd be more inclined to agree if the rear of the screen were always hot. My concern is that it runs hot unpredictably and seems to be independent of what's on screen. In my most recent drive, the display was showing Google Maps via Car Play, and was hot sometimes, not at others.

As I said, I'm not having any functional problems. The fact others have observed something similar is actually encouraging, since it could mean this is just normal operation.

Apologies. I went into more detail after I realized my quick response warranted more detail. I'll check once I get mine (which is at the port getting ready to set said), but I don't think this is an issue. Worst case I'll grab a Fleer thermal scope and take a look at what's going on.

I measured the temperature of both front and back of the display today. Dashboard temps were in the 80 degree F range while the display was as high as 110 - 115 degrees F on front and back. Not alarming but quite warm. I will look at this further as I am able.
