i have upgraded to a Sony head unit and selling my Scion unit, along with everything needed to install into a vehicle with the JBL with Synthesis stereo system. This kit allowed me to control the Scion unit using steering wheel buttons.
-Radio PT546-00120
-Pac TATO interface unit
-antenna splitter two into one
-OEM microphone
-all wiring needed to connect to a JBL synthesis system
My asking price is $100 .
Was this in your 80 or your 4runner, and what did it do for you? Bluetooth and steering wheel controls for the radio?
I'm looking to replace the radio in our '05 4Runner with something that has Apple CarPlay, Bluetooth connectivity to a phone and backup camera capability.
