Smartnav - Disassembling

[ng4xjs]

I’ve just taken the plunge and re-acquainted my self with an X Type. Always liked the model. This one is a 2.5 (04) and so far seems fine.

I have one thing I do want to sort. It has some sort of Smartnav fitted (Traffic Master) and this one seems to be active, although I am able to switch it off. It has what appears to be an aerial on the windscreen and some kind of receiver on top of the dash. I want to remove but (without dismantling the dash) don’t know where to start.

No reflection on Traffic Master but I’m not subscribed to their system and just need it disassembling and removed from my car. Any ideas?
