2017 RX350 Navigation Screen has numerous bubbles.

My navigation screen has a lot of small bubbles. It appears that parts of the screen are separating. Does not affect function but looks bad. Anyway to correct this other than replacing the whole unit?

Our 17 year-old RX400h screen has no bubbles. Perhaps you should show your dealership service representative to see if it's something Lexus will cover.
