$379.00 AP4-TY13 (R.2)
AmpPRO 4 Amplifier Integration Interface
  • Lexus ES250, ES350, and NX300: Only compatible in models equipped with the 8" screen
  • Lexus RX350 and RX450: Not compatible in models equipped with navigation
  • In 2018+ models Toyota used three different styles of connectors on the factory radios. In order for the AP4-TY13 to be compatible, the radio must have the 28 / 10-pin BHA1765 style connector. Vehicles equipped with the 20-pin BHA8113  or the 10 / 6 pin BHA1761 style connectors 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. Please see pictures below for reference.
