"The AFDI-THX-01 is designed to retain the THX audio system in the applications listed when replacing the OEM radio with an aftermarket one. Instead of using a turn on wire in the OEM harness, the OEM radio uses CAN data to turn the amplifier on and off. The CAN data also tells the OEM radio when the vehicle is on and off. Because of this, these vehicles do not have a traditional 12 volt accessory wire in the OEM harness. By reading the CAN data the AFDI-THX-01 will know when the vehicle is on and off and will provide a 12 volt 10 amp accessory output to be used by the aftermarket radio. Another feature of the AFDI-THX-01 is if the vehicle has the overhead video system the AFDI-THX-01 will keep that option active and allow the audio from that overhead to be played through the aftermarket radio; however the radio you install must have an auxiliary input to hear the audio from the overhead. Also if the vehicle has the 3.5mm aux jack the AFDI-THX-01 will retain that feature by providing a RCA output. If you are installing a radio that has navigation built in, the AFDI-THX-01 will provide the necessary navigation outputs like VSS (Speed Sense), Parking Brake, and Reverse. This will save installation time so the installer does not have to search through the vehicle to get these wires."
