I have a 2017 Outback without nav and without HK. I'd like to replace the HU with an aftermarket one to allow the use of Android Auto. However, I would also like to keep the factory backup camera. Is there a solution to do so? Crutchfield says there wiring harnesses to keep backup camera and steering wheel buttons do not work on the 2017 Outback, but the harness does work on the 2017 Forester. Are the internals of the two cars similar enough to where I can make it work on the Outback?
