Sharing another DIY video for setting custom images to appear on your Lexus heads up display. Tried to add some details based on some of the challenges I faced and hope it helps others.

 

does the USB need to stay connected once the images are set?

 

What should be the dimensions of the images so it spans the entire screen correctly (no distortions)? How about the newer models with the wider screen? Also can you restore the default images?

 

Sorry, thought that you had an option that is actually a heads up display. That appears to be the center display not a heads up display. Nice touch though.

 

The USB does not need to remain connected. The car comes with memory which can store up to 10 images! Although you can only set 1 at a time for either the Start sequence or Screen Off.

 

The dimensions which I used for my 2015 RC and presumably any other model which uses the same exact screen size would be 800x480. I cant comment on what it would be for a newer model with a larger screen, sorry.
Hope this helps!

 

You make a good point, I used the wrong terminology! It most definitely is the center display this mod is for.

 

Thanks for the DIY... I'm gonna try this today!
