Review on 🔌 Metra 70-8114: Steering Wheel Control Wire Harness with RCA for 2003-Up Toyota/Scion/Lexus Vehicles by Samiran Pusarla

My wife has a Lexus GX470 Non Nav / Non Mark Levinson sound system. Replaced factory head unit (Pioneer) with Binize 10.1 inch Android HU. I have a Metra TYTO-01 kit to connect the new HU to the factory wiring harness, but the steering wheel controls for the GX470 (and probably the Toyota 4-Runner) are on a separate 20-pin connector that plugs into the factory HU goes . Thanks to feedback from another user here I was able to hook up an Android (with SW1 and SW2 cables) to the factory harness. Here is an excerpt from another user's review: Of the 6 wires on the white connector, 3 are of interest. Black wire = GND (connect to the GND wire of the new head unit - this is the steering wheel control GND, not the main one -GND - you still need to connect the main ground of the PG) . Green/Yellow = SW1/KEY1, Green/Black = SW2/KEY2. This made it as easy as possible to get steering wheel controls working with the new Android HU. (end of review) From the Binize Android head unit, go to the settings page and there is a button on the left (scroll down) that shows steering wheel settings. Go there and you will see various settings (like Volume Up, Volume Down, FFWD, RWD, GPS, etc.). Select the desired function on the screen and then press the steering wheel button you want to perform. I programmed Vol+Vol-Next Track, Previous Track and set the mode button to GPS (which I set Waze to be my default GPS navigator). Steering wheel control works great, wife loves it!
