I bought my toyota sequoia used 10 years ago with Z110 installed and have had no issues until now. The backup camera started acting up few days ago that would give blurry images sometimes and would work fine the rest of the times, this lasted couple of days. Then it gradually became worse, would sometimes show the blurry image and other times completely blank screen when put in reverse. I am seeing completely blank image last couple of days and i think it might be completely dead now. Everything else (music, navigation etc) works fine. Any idea whats wrong?
