If your Lexus was equipped with OEM 360 Cameras (or the 2014-21 Lexus GX surround view style cameras), it is important to read this article.
This applies only to Conversion Kits (replacement screens).
Watch the following video for a wiring overview of the 360 camera box for Hamilton Conversion Kits. There are five essential connections that are easily overlooked.
If everything is connected but your cameras are not triggering, check the following settings (these should be preset from Hamilton fulfillment):
Navigate to Hamilton Settings > Advanced Settings > Enter 8868 > Car Camera > Change from "CVBS" to "LVDS." Do not change any other advanced settings, even if they seem intuitive. Doing so can irreversibly damage your device. Contact Hamilton Customer Support if issues persist.
