Yes, Apple CarPlay comes standard on the 2020 Impreza, Legacy, Crosstrek, Forester, Outback, Ascent, BRZ and WRX! Not only that, but the 2020 models support wireless CarPlay so no USB connections are necessary for pairing.
The 2020 Ascent features STARLINK Multimedia with standard Apple CarPlay®, Android Auto™. Wireless pairing and hands-free smartphone operation allow for safe and easy connection to your favorite apps and content.
According to above information Subaru's 2020 models now support Apple's CarPlay connected Wireless.
However, I have had no success in getting Subaru 2020 Ascent Limited Infotainment system to connected to CarPlay via BlueTooth.
Wondering now, if by Wireless, they mean Subaru's WiFi Hotspot?
I have tried using Subaru's StarLink, but it is mess. Every time we try to use navigation, it has to go through downloading maps, verifying license, safety acknowledgement, usually taking 3-minutes. Look at radio or get a call, and we have to start navigation all over.
CarPlay is our last hope.
Ascent is great vehicle, but Infotainment system is huge downer.
