The 2018 Subaru I bought has a "Starlink" media center that supports CarPlay. I have an iPhone 7, tethered to the player by USB. For various reasons I strongly prefer Google Maps to Apple Maps. However, if I'm playing anything in the foreground (radio, podcast) and Google Maps interrupts it with spoken instructions, the media doesn't resume playing afterward.
The problem doesn't happen when using Apple Maps.
There's very little documentation about how CarPlay, apps, and the media center co-operate. I was wondering if anyone could enlighten me as to how to make CarPlay work in this situation.
