LOSS OF BLUETOOTH & FUSE BOX

Bluetooth (2012 Superb 2l estate) soft key Bluetooth button, while present (top right hand side), is no longer green and every time connecting to my telephone when it asks to connect and offers four sets of the same numbers as code it is always rejected. I have no Bluetooth facility anymore. I have rebooted the Columbus twice and have disconnected the under drivers seat unit four times. No change. Ideas?

FUSE BOX Thought I'd look at fuses. Rather than destroy both of them trying to gain access what do you do to the two lock tabs on the box under the hood and what do you do with the screwdriver on the passenger side interior plastic cover?
