Yeah..!
That's exactly the same as mine... the sim adapter you get in the armrest perfectly fits the slot pictured there. Just keep in mind you need to cut the two "ears" of the adapter as they prevent it from being completely inserted in the slot.
If you give it a try you'll clearly see what I'm talking about.... easier to see it for yourself than trying to explain on here.

About pairing, keep in mind that such TCU is NOT a real Bluetooth unit and will NOT pair with every BT phone out there... it ONLY pairs with its motorola handset pictured HERE.
If you mix them from different cars or buy separately, I suppose some coding will be required in order to let handset and TCU meet themselves and pair succesfully... not sure about it though.
