RB10TAC16B, RB10TAC16HP, RB10TAC16X: Backup camera inop

If the radio doesn’t activate the backup camera screen when the vehicle is in reverse, it may indicate that the reverse wire has not been properly connected. On the radio-side harness of the PAC interface module, you will find bullet connectors on a Purple/White wire. Make sure these bullet connectors are connected according to the type of transmission in your vehicle.
