I had my display on my 07 RAV4 go wacko a couple of times. Of course, it wasn't going to happen while I was anywhere near the dealer (famous "could not duplicate" error). I took a picture of the display with my cell phone camera to the dealer. They ordered a new radio on the spot. Should be here in about a week. Note: There is a TSB out on display problems with many RAV4 radios. I don't know about problems with the TCH.
