2003-up Toyota Stereo Replacement for JBL Equipped Vehicles

The TA07SRC radio replacement interface was designed to make installation of any brand name aftermarket head-unit simple. The TA07SR allows the customer to replace the factory head unit with an aftermarket head unit and utilize their factory amplifier without having to "re-wire" the entire system.

The TA07SRC works with data driven JBL systems and JBL synthesis systems in select Toyota vehicles. Through thorough research, Scosche's radio replacement interface offers the "smartest" amplifier retention interface on the market with precision audio matching to factory amplifiers that actually recognizes what system it is being used with and adjusts itself accordingly to avoid distortion of factory speakers. The TA07SRC also offers balance control and fading for complete manual sound management. The unit has 4-channel RCA leads so the installer can use the RCA output of the stereo and gain the highest quality sound rather than go through the speaker level output. The 3 wire hard-wired RCA's are color coordinated for left right-front and rear speaker colors and easy installation.

If a customer wishes to retain the factory radio, Scosche also manufactures the Toyota auxiliary input iPod interface, AXIPTA for Toyota vehicles that retains all factory setting. The AXIPTA creates an auxiliary input on a factory stereo for an iPod player and integrates full iPod controls at the factory radio for vehicles with navigation head-units.

Product Features

  • Toyota stereo replacement for vehicles with Digital JBL/JBL Synthesis amplifiers
  • The TA07SRC digital interface will allow you to connect your aftermarket radio to a Toyota JBL/Premium Sound audio system.

Not sure of purpose

January 3, 2014

Installation instructions are confusing. Not sure why it is needed. Has to cut a lot of wires off the unit and connect Axxess ASWC-1 and parts of Metra 70-8113 to the connectors to make it work.
