Bluetooth module/aerial location?

[Cantata]

Quick question....

2012 A6 S-Line Avant 3.0 TDi.....does anyone know, please, where under the floor I would find the Bluetooth module? I'm told it's 'under the floor' but it would help if I knew where to look!

Suspect problem with the BT aerial. I assume it's in the same location as the module?!

Bumping this up to the top in the faint hope that someone knows the answer?

If it's under the floor a lot of modules are under the passenger front footwell I believe.
