Uniti 2 Upgrade whilst being repaired

Mu Uniti 2 has had the dreaded CD Err/continuous spinning without engaging for the second time.  Very embarrassing when your mates come round and laugh was on me you know the jokes.  Anyway the nice man at Naim said it is still under warranty so send it in for repair. I noticed that the new version has Bluetooth.  Does anyone know if you can get the WiFi only upgraded and if so how much and over what distance does it work. Just been given some Bluetooth headphones for birthday so would be nice if had the built-in kit instead of the dongle that you plug in. She goes in tomorrow.  I also presume they will give her the latest software updates too?  Thanks in appreciation.
