Product Research


USB Adapter Harness: The Axxess Integrate AX-SUBUSB2 USB adapter harness is used when you want to retain the factory USB port in select 2015-up Subaru vehicles, when replacing the factory radio with an aftermarket stereo that features a rear USB input.

Note: As long as your new car stereo has a high-amperage charging port (1.5A or greater), this USB adapter harness should support Apple CarPlay and Android Auto operation. However, the number of variables involved means we can't guarantee compatibility.

Will this adapter power both USB ports in the center console?

It would not work with my dual usb auxilliary jack but I was able to order a single usb jack from my dealer. The part # 86257AL21A, was only around $20. Now I can use carplay and charge my iphone. (2016 Outback)

Johnathan D's answer is right IF in your car the center console ("middle compartment where your arm is") has a SINGLE usb auxiliary port. But if your car has the dual usb auxiliary port (e.g., part # 86257AL200) in the center console, I do not believe this cable will work for you. One solution in that case would be to swap in a single usb port (e.g., part # 86257AJ201 or 86257AL21A) for your dual usb port, and then use this cable -- like Brendan M explains in another answer here. Hope that helps. Good luck!

This cable did not work in my 2017 Forester since it has 2 usb ports to connect. It should work with vehicles with only one usb connection. I have the AX-SUBUSB1 in my 2011 STi and it does connect and uses Carplay. If it works on your vehicle CarPlay will work. It is a convenient spot in the center console. Good luck, John

You can not use carplay/android auto with this.
jeff  May 27, 2020

Yes. It worked for me.

Let's say your car (Subaru) has a USB port in the middle compartment where you arm is. This cable is an adapter that allows you to connect that USB port to the new headunit that you would have bought. Once you plug in your car USB port into this cable, then this cable into the headunit, you can use your middle compartment usb port to plug into your phone and then use carplay with the headunit.
