About the iDatalink ACC-USB-SU1 Adapter for Subaru

Keep your Subaru's USB port

Metra's ACC-USB-SU1 cable allows you to keep the USB port in your Subaru when you install a new car stereo. One end of the cable connects to the plug just behind the USB port on your vehicle's console, while the other end plugs into the USB port on your new car stereo (it must have a rear USB port). The package also retains your Subaru's 3.5mm jack, if your new radio has a rear AUX input. Warranty: 1 year.

What's in the box:

  • 59" Aux harness (terminated by a molex connector on one end and a male stereo 3.5mm connector on other end)
  • 20" USB harness (terminated by a molex connector on one end and a male USB-A connector on other end)

Customer Q&A

Will this fit a non-nav 2010 forester?
[ John  Mar 05, 2020 ]

The supplied 3.5mm cable connector is TOO SHORT. I have a 2013 Subaru Forester, originally came with non-navigation head unit (OEM Clarion) and 6 speakers. I purchased a Kenwood Excelon multimedia unit from Crutchfield along with the ACC-USB-SU1. The USB connector is fine (I purchased an add'l USB cord from Apple to use in the cabin just in case), while I had to purchase an 18" right angle 3.5mm audio cable extension to complete the radio installation.
[ Robert  Dec 09, 2020 ]
Yes it does. You would likely need some additional wiring to complete a radio installation. You can connect with one of our product advisors to get a complete cart here:
