Admittedly, mine was an older model. Idk how old, it was in the truck when I bought it but I had the book and there was no adjustment for this one. It was the Concours Series USA-230 (I'm actually looking at the book now lol, my buddy that bought it from me forgot to grab the book). Our shop truck has the same one in it, no option for brightness adjustmentThanks for posting that picture. I was looking at them or Retro Sound. If there is no option to dim that display then I will find something else.
@totallyhucked Not sure which model radio you have but see the instructions, page 11, for Custom Autosound radio. It shows there are 7 brightness levels. Instructions
