Yes it's possible, not easy though. You can buy the antenna from VW for 200 bucks or aftermarket for much cheaper. You will also need the wiring harness which you can get on ebay for 35 bucks or so. It is plug and play on the reciever (on the 510's at least) There are 2 antenna ports. One for the radio antenna and one for sirius/nav which is the phaeton antenna. Big thing to me would be drilling a big ass whole in my roof.
