I've had the MC2000 for years, recently got the NC2010 and it is streets ahead of the old model.
I got one from ebay.de for £500 delivered, a 2011 unit. Integrated Parrot bluetooth and decent nav, nothing can compare at that price.
It also shows info on the highline, and digital aircon/parking sensors if you have those fitted.
Make sure it has all the kit (GPS antenna, TMC box, USB box etc).
A new update came out last week so put that on if you get it.
Also ask for the security code if activated and changed!
