Hello I recently purchased a sport 2006 2.7 S it doesn't have sat nav, how can I get sat nav in? Software update? Total new unit?

Thanks

Buy a Tom Tom or aftermarket system and stick it in the slot. To retrofit an OEM style Nav System would be very expensive and not easy.

If you get a tomtom you can use the 'home mount' with the fitted USB lead. This is normally meant to hook up to your PC. Pull off your centre radio console surround, the bit you left knee can touch to the side, it just clicks out and the feed the wiring behind and out to the 12v socket. It looks neat and is easy to remove or cover. The TT XXL is the biggest screen but doesn't have all the phone bluetooth and live traffic. I did this on my Disco 3 S and it was fine.
