$379.00 AP4-TY11
AmpPRO 4 Amplifier Integration Interface

Vehicles with Telematics (ie: SOS, Enform, etc) will require some additional wiring. See manual for details.

  • Toyota vehicle must be equipped with a JBL system. There must be an actual visible label that says JBL or JBL Synthesis. If the vehicle is equipped with a factory amplifier but does not say JBL, it is not compatible because the amplifier is analog and not digital.
  • 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.
