  • Lexus vehicles must be equipped with a center channel and a subwoofer in order for the AP4-TY11 to be compatible:
  • Between 2012-2015 Toyota used two different styles of connectors. In order for the AP4-TY11 to be compatible, the radio must have the 20-pin BHA8113 style connector. Vehicles equipped with the 10 / 6-pin BHA1761 style connector are not compatible. The only way to know what connector the radio has is to physically remove it from the dash and look at it.
