Yes. There is the antenna end which is stuck inside the armrest on a velcro strap, (I think this is the BTUM unit? Whatever it is called it`s a pain in the backside to get at!!). Which is where you take the ashtray out, screws, pop out the gear gaiter, pop off the carpet trims on either side and take out more screws (Torx screws allover the place), also inside the cubby box there is a rubber mat that you pull out and find MORE screws.. Eventually you can lift up the armrest and reach under the cubby box and feel in under there, the antenna/BTUM unit is black plastic. The silver module further to the front of the armrest is the airbag module don`t mess with that... The actual bluetooth `module` is located in the rear boot, around the area where the cd changer and sat nav disc unit are. Try disconnecting both and leaving them for a few hours, then reconnect everything back up and see if it helps. If not either one may need replacing.. Or there is a fault with the wiring inbetween.. I am currently trying to fix mine also! I have disconnected the antenna end, but not the module in the boot yet. Let me know how you get on and I will let you know if I have any success!
