You should see the the wireless charging logo next to the 12v sockets. There is also an option in the menu to disable/enable it. I haven't tested mine because my phone doesn't have it.
Mines works fine! Light comes on between the 12v sockets when charging!
What phones are compatible mate? We have iPhone 6’s but they’re not. I kinda, stupidly, thought any phone would charge! Duh.
