Subaru Outback/Legacy 2015-2019 Android/Apple CarPlay head unit update 

I like it a lot. Big improvement to the stock one. Bluetooth connection is fast and the sound is so much louder. The only thing that I don't like is that the startup time is a bit slow, mostly first time in the day and when you are in a hurry and reverse camera doesn't come up right away. It takes like 10s -20s.

10-20s is unacceptable

Yes but it needs an extra harness. When ordering from autoharness you can select. Even from cruchfield.

If you don't want to splice wires you need to buy the plug and play harnesses.
