WIRELESS CARPLAY STOPPED WORKING [UPDATE: SOLVED] | MachEforum - Ford Mustang Mach-E News, Owners, Discussions, Community
I figured out there is a second hotsport wifi named "PROjb3e11" that has to have "auto-Join" selected or wireless Carplay will never work. This is a different SSID if you subscribe to AT&T hotspot built into the Mach-E. It took a senior Apple "Genius" to figure this out. Ford tech should be aware of this. You need both a wifi and Bluetooth connection in order for wireless Carplay to work and you will have to manually set the "Auto Join" even after re-pairing the Bluetooth connection.
