RED WOLF Car Radio Factory USB Port Retention Cable Wiring Harness Fit for 2011-2022 Subaru WRX Impreza Forester Outback Retain OE USB Wire Adapter Install Aftermarket Stereo Head Unit 4 Pin Input

Fits and works perfectly for adapting the factory USB.

Fit nicely in my 2015 Subaru Legacy

I installed this with all my Idoing head unit I purchased for my 2017 Subaru Outback. This cable allowed me to use the the built-in USB ports located in the storage area under the climate controls.

This adapter let me use my OEM USB port with an aftermarket head unit, as intended. My only complaint is that the fit is a little bit loose, which is concerning when this thing lives in the rat's nest of cables crammed inside of your dash. You can always just tape it up with electrical tape, but it would be nice if it had a reassuringly snug fit, so as not to come loose while driving over potholes.

Works great

It allows you to retain the original USB port, but it's a thin cable and kind of cheap (the connector housing slides off the metal part with regular use).That being said, adding this (thin) cable in line with the OEM cable makes Android Auto very unstable, so -at least in my case- it's a waste of money.If you are considering this cable after installing an aftermarket radio, you are probably better just replacing the USB port altogether.

This was the answer to my problem.

Perfect fit to adapt the stock USB port on a 2012 Subaru WRX over to an aftermarket head unit. I used this on a Idoing 9"Android Radio Head Unit For Subaru Forester WRX 2008-2014 PPP2299. Must go into the single USB port not the double port in the Idoing.
