L322 CJB (Central junction box) infotainment system

Hi Guy's, my 2011 L322 has had a fault with the bluetooth since ive had it & now its time to sort it out.

Ive got a wiring diagram which actually shows that the live feed to the bluetooth is straight off the battery, but actually goes through the CJB. does anyone know if the CJB reboots any of the infotainment system?

Many thanks in advance

Could you tell me where you found the wiring diagram please. I have been looking for one for my 2009 model
