I havent seen one of the RNS go for less than £600 recently (which is 50% more), and most of them at that price seem to be reconditioned from lithuania which i dont fancy and i dont really need the sat nav as i fairly recently got a High-end Tom Tom Live, which i think is a better sat nav unit.
The slightly annoying thing is, having removed my air vents and the Airbad on/off plug I now have an airbag fault, hopefully my dealer will reset this for nothing as i spent a fortune there recently, annoying though, should have thought about it!
