Got one of these for sale, used but in mint condition. Worked fine in the car before it got removed and it was professionally installed from new.
£250 on Ebay for a brand new one, and after looking at the link above, that half the price anyway.
This is a complex Satnav, not the usual touch-screen only satnav's that you see around.
The link above tells you basically everything you need to know about it.

Looking for £80.00 delivered, but open to offers.
