This is the Data System camera adapter RAC003T. It's a device that converts a Toyota 4P camera to a general-purpose RCA connection. It's useful when using a Toyota genuine camera (without viewpoint change) with an aftermarket navigation system that has an RCA input for a backup camera. The new model has a smaller body than the previous model. Operation has been confirmed. Please check the Data System website for a compatibility chart to see if the adapter is suitable for your vehicle's camera. 250723-z1
