A:Answer Hi Mo, Unfortunately, our BRAVIA CAM is not compatible with our BRAVIA A90J. You can connect the BRAVIA CAM (CMU-BC1) with these BRAVIA models: Z9K, X95K, A95K, A90K, A80K, X90K, X85K, X80K. Our BRAVIA A90J features COGNITIVE PROCESSOR XR, a revolutionary TV processing technology that understands how humans see and hear to deliver intense contrast with pure blacks, high peak brightness, and natural colors. You will feel immersive depth and realism with ultimate blacks and our brightest-ever OLED picture with its XR OLED CONTRAST PRO feature. Thank you for your inquiry and I hope this helps! Vincent
