Perfect working condition. It's been a fantastic head unit and I would be keeping it if my truck didn't come with a nav unit. Looking to get $300 The faceplate is detachable if you need the security It will come with the wire harness for an 07 sti. I'm not sure what other years match but I'd assume it's a few. It doesn't have NAV but it supports apple play and will announce your directions if you don't have apple car play going. HD radio is nice and comes in clear. Touch screen is responsive and works great Lots of customization available within the system to make it your own user experience.
