Hi

I appreciate this will be a niche problem but I have a 2018 Subaru Outback (MY17 Model) which has Mirrorlink as the way to connect a phone to the infotainment screen.  The mirrorlink icon is greyed out and I haven't managed to figure out a way to connect my phone to it (the phone itselt  a Samsung s8 says its connected to the car via mirrorlink).

When I contacted Subaru about it they have said this functionality is no longer available- which for a car less than a year old is pretty poor I would have thought.  The current newer model comes with android auto/apple carplay.  Any ideas how I could update the firmware?

thanks
