Camera not working after installation


  • Just installed the CarPlay unit in my 2017 Lexus Rx350. Everything works with the exception of my camera. I triple checked that the yellow wire was correctly connected, yet when I go in reverse I get a gray blank screen. I do not have the 360 camera either. Any suggestions?



  • Hi Spencer,

    Thanks for bringing this to our attention. I believe our support team was able to assist you with this over email. Thanks


  • Having the same issue, same car, what was the fix? Thanks


  • Whether you have the mouse or knob version, download our wiring diagram here at

    Ususally when the backup camera is not working it's because you have forgotten to connect the thick black connector from the back of the factory screen. On the knob version it connects to the female socket labeled OEM Camera. On the mouse version it connects to the female socket labeled "Monitor."
