I am using a similar gadget in my X type estate, but I have plugged the blue tooth gadget into the 12v supply in the boot space, leaves the supply in the ashtray clear for my phone or whatever.
It works really well, I use an old ipod for my music via Bluetooth gadget,but then use my phone via Bluetooth to the car phone system as usual.
