Hi @FrankEllis, welcome to the Best Buy Community forum
I'm not sure I understand your question, however I presume you have a unit from iRV technologies, model IRV33, which is an RV radio/CD unit , that you want to interface with an Insignia Home Theater system, in your RV.
I located an owner manual for the iRV 33, and depending on the model of the Insignia Home theater system, you will need to connect the RCA or HDMI output connectors from the rear of the IRV33, to the Insignia's Aux. input .
Can you provide the model of the Insignia Home Theater system?
